An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-10876, CVE-2018-10879) Wen Xu discovered that a buffer overflow existed in the ext4 filesystem implementation in the Linux kernel. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-10877) Wen Xu discovered that an out-of-bounds write vulnerability existed in the ext4 filesystem implementation in the Linux kernel. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-10878, CVE-2018-10882) Wen Xu discovered that the ext4 filesystem implementation in the Linux kernel did not properly ensure that xattr information remained in inode bodies. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service (system crash). (CVE-2018-10880) Wen Xu discovered that the ext4 file system implementation in the Linux kernel could possibly perform an out of bounds write when updating the journal for an inline file. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service (system crash). (CVE-2018-10883) It was discovered that a race condition existed in the vsock address family implementation of the Linux kernel that could lead to a use-after-free condition. A local attacker in a guest virtual machine could use this to expose sensitive information (host machine kernel memory). (CVE-2018-14625) Cfir Cohen discovered that a use-after-free vulnerability existed in the KVM implementation of the Linux kernel, when handling interrupts in environments where nested virtualization is in use (nested KVM virtualization is not enabled by default in Ubuntu kernels).

(CVE-2018-16882) Jann Horn discovered that the procfs file system implementation in the Linux kernel did not properly restrict the ability to inspect the kernel stack of an arbitrary task. A local attacker could use this to expose sensitive information. (CVE-2018-17972) Jann Horn discovered that the mremap() system call in the Linux kernel did not properly flush the TLB when completing, potentially leaving access to a physical page after it has been released to the page allocator. A local attacker could use this to cause a denial of service (system crash), expose sensitive information, or possibly execute arbitrary code. (CVE-2018-18281) Wei Wu discovered that the KVM implementation in the Linux kernel did not properly ensure that ioapics were initialized.

    descriptionThe SUSE Linux Enterprise 12 SP1 kernel was updated receive various security and bugfixes. The following security bugs were fixed : CVE-2018-14634: Prevent integer overflow in create_elf_tables that allowed a local attacker to exploit this vulnerability via a SUID-root binary and obtain full root privileges (bsc#1108912) CVE-2018-14617: Prevent NULL pointer dereference and panic in hfsplus_lookup() when opening a file (that is purportedly a hard link) in an hfs+ filesystem that has malformed catalog data, and is mounted read-only without a metadata directory (bsc#1102870) CVE-2018-16276: Incorrect bounds checking in the yurex USB driver in yurex_read allowed local attackers to use user access read/writes to crash the kernel or potentially escalate privileges (bsc#1106095) CVE-2018-12896: Prevent integer overflow in the POSIX timer code that was caused by the way the overrun accounting works. Depending on interval and expiry time values, the overrun can be larger than INT_MAX, but the accounting is int based. This basically made the accounting values, which are visible to user space via timer_getoverrun(2) and siginfo::si_overrun, random. This allowed a local user to cause a denial of service (signed integer overflow) via crafted mmap, futex, timer_create, and timer_settime system calls (bnc#1099922) CVE-2018-13093: Prevent NULL pointer dereference and panic in lookup_slow() on a NULL inode->i_ops pointer when doing pathwalks on a corrupted xfs image. This occured because of a lack of proper validation that cached inodes are free during allocation (bnc#1100001) CVE-2018-10940: The cdrom_ioctl_media_changed function allowed local attackers to use a incorrect bounds check in the CDROM driver CDROM_MEDIA_CHANGED ioctl to read out kernel memory (bsc#1092903) CVE-2018-16658: Prevent information leak in cdrom_ioctl_drive_status that could have been used by local attackers to read kernel memory (bnc#1107689) CVE-2018-6555: The irda_setsockopt function allowed local users to cause a denial of service (ias_object use-after-free and system crash) or possibly have unspecified other impact via an AF_IRDA socket (bnc#1106511) CVE-2018-6554: Prevent memory leak in the irda_bind function that allowed local users to cause a denial of service (memory consumption) by repeatedly binding an AF_IRDA socket (bnc#1106509) CVE-2018-10902: Protect against concurrent access to prevent double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status(). A malicious local attacker could have used this for privilege escalation (bnc#1105322) CVE-2018-10879: A local user could have caused a use-after-free in ext4_xattr_set_entry function and a denial of service or unspecified other impact by renaming a file in a crafted ext4 filesystem image (bsc#1099844) CVE-2018-10883: A local user could have caused an out-of-bounds write in jbd2_journal_dirty_metadata(), a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image (bsc#1099863) CVE-2018-10880: Prevent stack-out-of-bounds write in the ext4 filesystem code when mounting and writing to a crafted ext4 image in ext4_update_inline_data(). An attacker could have used this to cause a system crash and a denial of service (bsc#1099845) CVE-2018-10882: A local user could have caused an out-of-bound write, a denial of service, and a system crash by unmounting a crafted ext4 filesystem image (bsc#1099849) CVE-2018-10881: A local user could have caused an out-of-bound access in ext4_get_group_info function, a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image (bsc#1099864) CVE-2018-10877: Prevent out-of-bound access in the ext4_ext_drop_refs() function when operating on a crafted ext4 filesystem image (bsc#1099846) CVE-2018-10876: A use-after-free was possible in ext4_ext_remove_space() function when mounting and operating a crafted ext4 image (bsc#1099811) CVE-2018-10878: A local user could have caused an out-of-bounds write and a denial of service or unspecified other impact by mounting and operating a crafted ext4 filesystem image (bsc#1099813) CVE-2018-10853: The KVM hypervisor did not check current privilege(CPL) level while emulating unprivileged instructions. An unprivileged guest user/process could have used this flaw to potentially escalate privileges inside guest (bsc#1097104). The update package also includes non-security fixes.

The following security bugs were fixed :

CVE-2018-14634: Prevent integer overflow in create_elf_tables that
allowed a local attacker to exploit this vulnerability via a SUID-root
binary and obtain full root privileges (bsc#1108912)

CVE-2018-14617: Prevent NULL pointer dereference and panic in
hfsplus_lookup() when opening a file (that is purportedly a hard link)
in an hfs+ filesystem that has malformed catalog data, and is mounted
read-only without a metadata directory (bsc#1102870)

CVE-2018-16276: Incorrect bounds checking in the yurex USB driver in
yurex_read allowed local attackers to use user access read/writes to
crash the kernel or potentially escalate privileges (bsc#1106095)

CVE-2018-12896: Prevent integer overflow in the POSIX timer code that
was caused by the way the overrun accounting works. Depending on
interval and expiry time values, the overrun can be larger than
INT_MAX, but the accounting is int based. This basically made the
accounting values, which are visible to user space via
timer_getoverrun(2) and siginfo::si_overrun, random. This allowed a
local user to cause a denial of service (signed integer overflow) via
crafted mmap, futex, timer_create, and timer_settime system calls
(bnc#1099922)

CVE-2018-13093: Prevent NULL pointer dereference and panic in
lookup_slow() on a NULL inode->i_ops pointer when doing pathwalks on a
corrupted xfs image. This occured because of a lack of proper
validation that cached inodes are free during allocation (bnc#1100001)

CVE-2018-10940: The cdrom_ioctl_media_changed function allowed local
attackers to use a incorrect bounds check in the CDROM driver
CDROM_MEDIA_CHANGED ioctl to read out kernel memory (bsc#1092903)

CVE-2018-16658: Prevent information leak in cdrom_ioctl_drive_status
that could have been used by local attackers to read kernel memory
(bnc#1107689)

CVE-2018-6555: The irda_setsockopt function allowed local users to
cause a denial of service (ias_object use-after-free and system crash)
or possibly have unspecified other impact via an AF_IRDA socket
(bnc#1106511)

CVE-2018-6554: Prevent memory leak in the irda_bind function that
allowed local users to cause a denial of service (memory consumption)
by repeatedly binding an AF_IRDA socket (bnc#1106509)

CVE-2018-10902: Protect against concurrent access to prevent double
realloc (double free) in snd_rawmidi_input_params() and
snd_rawmidi_output_status(). A malicious local attacker could have
used this for privilege escalation (bnc#1105322)

CVE-2018-10879: A local user could have caused a use-after-free in
ext4_xattr_set_entry function and a denial of service or unspecified
other impact by renaming a file in a crafted ext4 filesystem image
(bsc#1099844)

CVE-2018-10883: A local user could have caused an out-of-bounds write
in jbd2_journal_dirty_metadata(), a denial of service, and a system
crash by mounting and operating on a crafted ext4 filesystem image
(bsc#1099863)

CVE-2018-10880: Prevent stack-out-of-bounds write in the ext4
filesystem code when mounting and writing to a crafted ext4 image in
ext4_update_inline_data(). An attacker could have used this to cause a
system crash and a denial of service (bsc#1099845)

CVE-2018-10882: A local user could have caused an out-of-bound write,
a denial of service, and a system crash by unmounting a crafted ext4
filesystem image (bsc#1099849)

CVE-2018-10881: A local user could have caused an out-of-bound access
in ext4_get_group_info function, a denial of service, and a system
crash by mounting and operating on a crafted ext4 filesystem image
(bsc#1099864)

CVE-2018-10877: Prevent out-of-bound access in the
ext4_ext_drop_refs() function when operating on a crafted ext4
filesystem image (bsc#1099846)

CVE-2018-10876: A use-after-free was possible in
ext4_ext_remove_space() function when mounting and operating a crafted
ext4 image (bsc#1099811)

CVE-2018-10878: A local user could have caused an out-of-bounds write
and a denial of service or unspecified other impact by mounting and
operating a crafted ext4 filesystem image (bsc#1099813)

CVE-2018-10853: The KVM hypervisor did not check current
privilege(CPL) level while emulating unprivileged instructions. An
unprivileged guest user/process could have used this flaw to
potentially escalate privileges inside guest (bsc#1097104).

The update package also includes non-security fixes. See advisory for
details.

    descriptionThe SUSE Linux Enterprise 12 SP3 azure kernel was updated to 4.4.155 to receive various security and bugfixes. The following security bugs were fixed : CVE-2018-13093: Prevent NULL pointer dereference and panic in lookup_slow() on a NULL inode->i_ops pointer when doing pathwalks on a corrupted xfs image. This occured because of a lack of proper validation that cached inodes are free during allocation (bnc#1100001) CVE-2018-13095: Prevent denial of service (memory corruption and BUG) that could have occurred for a corrupted xfs image upon encountering an inode that is in extent format, but has more extents than fit in the inode fork (bnc#1099999) CVE-2018-13094: Prevent OOPS that may have occured for a corrupted xfs image after xfs_da_shrink_inode() is called with a NULL bp (bnc#1100000) CVE-2018-12896: Prevent integer overflow in the POSIX timer code that was caused by the way the overrun accounting works. Depending on interval and expiry time values, the overrun can be larger than INT_MAX, but the accounting is int based. This basically made the accounting values, which are visible to user space via timer_getoverrun(2) and siginfo::si_overrun, random. This allowed a local user to cause a denial of service (signed integer overflow) via crafted mmap, futex, timer_create, and timer_settime system calls (bnc#1099922) CVE-2018-16658: Prevent information leak in cdrom_ioctl_drive_status that could have been used by local attackers to read kernel memory (bnc#1107689) CVE-2018-10940: The cdrom_ioctl_media_changed function allowed local attackers to use a incorrect bounds check in the CDROM driver CDROM_MEDIA_CHANGED ioctl to read out kernel memory (bsc#1092903) CVE-2018-6555: The irda_setsockopt function allowed local users to cause a denial of service (ias_object use-after-free and system crash) or possibly have unspecified other impact via an AF_IRDA socket (bnc#1106511) CVE-2018-6554: Prevent memory leak in the irda_bind function that allowed local users to cause a denial of service (memory consumption) by repeatedly binding an AF_IRDA socket (bnc#1106509) CVE-2018-1129: A flaw was found in the way signature calculation was handled by cephx authentication protocol. An attacker having access to ceph cluster network who is able to alter the message payload was able to bypass signature checks done by cephx protocol (bnc#1096748) CVE-2018-1128: It was found that cephx authentication protocol did not verify ceph clients correctly and was vulnerable to replay attack. Any attacker having access to ceph cluster network who is able to sniff packets on network can use this vulnerability to authenticate with ceph service and perform actions allowed by ceph service (bnc#1096748) CVE-2018-10938: A crafted network packet sent remotely by an attacker forced the kernel to enter an infinite loop in the cipso_v4_optptr() function leading to a denial-of-service (bnc#1106016) CVE-2018-15572: The spectre_v2_select_mitigation function did not always fill RSB upon a context switch, which made it easier for attackers to conduct userspace-userspace spectreRSB attacks (bnc#1102517) CVE-2018-10902: Protect against concurrent access to prevent double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status(). A malicious local attacker could have used this for privilege escalation (bnc#1105322). CVE-2018-9363: Prevent buffer overflow in hidp_process_report (bsc#1105292) CVE-2018-10883: A local user could have caused an out-of-bounds write in jbd2_journal_dirty_metadata(), a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image (bsc#1099863) CVE-2018-10879: A local user could have caused a use-after-free in ext4_xattr_set_entry function and a denial of service or unspecified other impact by renaming a file in a crafted ext4 filesystem image (bsc#1099844) CVE-2018-10878: A local user could have caused an out-of-bounds write and a denial of service or unspecified other impact by mounting and operating a crafted ext4 filesystem image (bsc#1099813) CVE-2018-10876: A use-after-free was possible in ext4_ext_remove_space() function when mounting and operating a crafted ext4 image (bsc#1099811) CVE-2018-10877: Prevent out-of-bound access in the ext4_ext_drop_refs() function when operating on a crafted ext4 filesystem image (bsc#1099846) CVE-2018-10881: A local user could have caused an out-of-bound access in ext4_get_group_info function, a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image (bsc#1099864) CVE-2018-10882: A local user could have caused an out-of-bound write, a denial of service, and a system crash by unmounting a crafted ext4 filesystem image (bsc#1099849) CVE-2018-10880: Prevent stack-out-of-bounds write in the ext4 filesystem code when mounting and writing to a crafted ext4 image in ext4_update_inline_data(). An attacker could have used this to cause a system crash and a denial of service (bsc#1099845) The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The following security bugs were fixed :

CVE-2018-13093: Prevent NULL pointer dereference and panic in
lookup_slow() on a NULL inode->i_ops pointer when doing pathwalks on a
corrupted xfs image. This occured because of a lack of proper
validation that cached inodes are free during allocation (bnc#1100001)

CVE-2018-13095: Prevent denial of service (memory corruption and BUG)
that could have occurred for a corrupted xfs image upon encountering
an inode that is in extent format, but has more extents than fit in
the inode fork (bnc#1099999)

CVE-2018-13094: Prevent OOPS that may have occured for a corrupted xfs
image after xfs_da_shrink_inode() is called with a NULL bp
(bnc#1100000)

CVE-2018-12896: Prevent integer overflow in the POSIX timer code that
was caused by the way the overrun accounting works. Depending on
interval and expiry time values, the overrun can be larger than
INT_MAX, but the accounting is int based. This basically made the
accounting values, which are visible to user space via
timer_getoverrun(2) and siginfo::si_overrun, random. This allowed a
local user to cause a denial of service (signed integer overflow) via
crafted mmap, futex, timer_create, and timer_settime system calls
(bnc#1099922)

CVE-2018-16658: Prevent information leak in cdrom_ioctl_drive_status
that could have been used by local attackers to read kernel memory
(bnc#1107689)

CVE-2018-10940: The cdrom_ioctl_media_changed function allowed local
attackers to use a incorrect bounds check in the CDROM driver
CDROM_MEDIA_CHANGED ioctl to read out kernel memory (bsc#1092903)

CVE-2018-6555: The irda_setsockopt function allowed local users to
cause a denial of service (ias_object use-after-free and system crash)
or possibly have unspecified other impact via an AF_IRDA socket
(bnc#1106511)

CVE-2018-6554: Prevent memory leak in the irda_bind function that
allowed local users to cause a denial of service (memory consumption)
by repeatedly binding an AF_IRDA socket (bnc#1106509)

CVE-2018-1129: A flaw was found in the way signature calculation was
handled by cephx authentication protocol. An attacker having access to
ceph cluster network who is able to alter the message payload was able
to bypass signature checks done by cephx protocol (bnc#1096748)

CVE-2018-1128: It was found that cephx authentication protocol did not
verify ceph clients correctly and was vulnerable to replay attack. Any
attacker having access to ceph cluster network who is able to sniff
packets on network can use this vulnerability to authenticate with
ceph service and perform actions allowed by ceph service (bnc#1096748)

CVE-2018-10938: A crafted network packet sent remotely by an attacker
forced the kernel to enter an infinite loop in the cipso_v4_optptr()
function leading to a denial-of-service (bnc#1106016)

CVE-2018-15572: The spectre_v2_select_mitigation function did not
always fill RSB upon a context switch, which made it easier for
attackers to conduct userspace-userspace spectreRSB attacks
(bnc#1102517)

CVE-2018-10902: Protect against concurrent access to prevent double
realloc (double free) in snd_rawmidi_input_params() and
snd_rawmidi_output_status(). A malicious local attacker could have
used this for privilege escalation (bnc#1105322).

CVE-2018-9363: Prevent buffer overflow in hidp_process_report
(bsc#1105292)

CVE-2018-10883: A local user could have caused an out-of-bounds write
in jbd2_journal_dirty_metadata(), a denial of service, and a system
crash by mounting and operating on a crafted ext4 filesystem image
(bsc#1099863)

CVE-2018-10879: A local user could have caused a use-after-free in
ext4_xattr_set_entry function and a denial of service or unspecified
other impact by renaming a file in a crafted ext4 filesystem image
(bsc#1099844)

CVE-2018-10878: A local user could have caused an out-of-bounds write
and a denial of service or unspecified other impact by mounting and
operating a crafted ext4 filesystem image (bsc#1099813)

CVE-2018-10876: A use-after-free was possible in
ext4_ext_remove_space() function when mounting and operating a crafted
ext4 image (bsc#1099811)

CVE-2018-10877: Prevent out-of-bound access in the
ext4_ext_drop_refs() function when operating on a crafted ext4
filesystem image (bsc#1099846)

CVE-2018-10881: A local user could have caused an out-of-bound access
in ext4_get_group_info function, a denial of service, and a system
crash by mounting and operating on a crafted ext4 filesystem image
(bsc#1099864)

CVE-2018-10882: A local user could have caused an out-of-bound write,
a denial of service, and a system crash by unmounting a crafted ext4
filesystem image (bsc#1099849)

CVE-2018-10880: Prevent stack-out-of-bounds write in the ext4
filesystem code when mounting and writing to a crafted ext4 image in
ext4_update_inline_data(). An attacker could have used this to cause a
system crash and a denial of service (bsc#1099845)

The update package also includes non-security fixes. See advisory for

"According to the versions of the kernel packages installed, the
EulerOS Virtualization installation on the remote host is affected by
the following vulnerabilities :

  - A new software page cache side channel attack scenario
    was discovered in operating systems that implement the
    very common 'page cache' caching mechanism. A malicious
    user/process could use 'in memory' page-cache knowledge
    to infer access timings to shared memory and gain
    knowledge which can be used to reduce effectiveness of
    cryptographic strength by monitoring algorithmic
    behavior, infer access patterns of memory to determine
    code paths taken, and exfiltrate data to a blinded
    attacker through page-granularity access times as a
    side-channel.i1/4^CVE-2019-5489i1/4%0

  - An issue was discovered in the proc_pid_stack function
    in fs/proc/base.c in the Linux kernel. An attacker with
    a local account can trick the stack unwinder code to
    leak stack contents to userspace. The fix allows only
    root to inspect the kernel stack of an arbitrary
    task.i1/4^CVE-2018-17972i1/4%0

  - A flaw was found in the Linux kernel's ext4 filesystem.
    A local user can cause an out-of-bound write in
    jbd2_journal_dirty_metadata(), a denial of service, and
    a system crash by mounting and operating on a crafted
    ext4 filesystem image.i1/4^CVE-2018-10883i1/4%0

  - A flaw was found in the Linux kernel's ext4 filesystem.
    A local user can cause an out-of-bounds write and a
    denial of service or unspecified other impact is
    possible by mounting and operating a crafted ext4
    filesystem image.i1/4^CVE-2018-10878i1/4%0

  - A flaw was found in the Linux kernel's ext4 filesystem.
    A local user can cause a use-after-free in
    ext4_xattr_set_entry function and a denial of service
    or unspecified other impact may occur by renaming a
    file in a crafted ext4 filesystem
    image.i1/4^CVE-2018-10879i1/4%0

  - A flaw was found in the Linux kernel's ext4 filesystem.
    A local user can cause an out-of-bound access in
    ext4_get_group_info function, a denial of service, and
    a system crash by mounting and operating on a crafted
    ext4 filesystem image.i1/4^CVE-2018-10881i1/4%0

  - An issue was discovered in the XFS filesystem in
    fs/xfs/libxfs/xfs_attr_leaf.c in the Linux kernel. A
    NULL pointer dereference may occur for a corrupted xfs
    image after xfs_da_shrink_inode() is called with a NULL
    bp. This can lead to a system crash and a denial of
    service.i1/4^CVE-2018-13094i1/4%0

  - An issue was discovered in the XFS filesystem in
    fs/xfs/xfs_icache.c in the Linux kernel. There is a
    NULL pointer dereference leading to a system panic in
    lookup_slow() on a NULL inode-i1/4zi_ops pointer when
    doing pathwalks on a corrupted xfs image. This occurs
    because of a lack of proper validation that cached
    inodes are free during an
    allocation.i1/4^CVE-2018-13093i1/4%0

  - In the Linux kernel before 4.17, a local attacker able
    to set attributes on an xfs filesystem could make this
    filesystem non-operational until the next mount by
    triggering an unchecked error condition during an xfs
    attribute change, because xfs_attr_shortform_addname in
    fs/xfs/libxfs/xfs_attr.c mishandles ATTR_REPLACE
    operations with conversion of an attr from short to
    long form.i1/4^CVE-2018-18690i1/4%0

"An update for kernel is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

Security Fix(es) :

* A flaw named FragmentSmack was found in the way the Linux kernel
handled reassembly of fragmented IPv4 and IPv6 packets. A remote
attacker could use this flaw to trigger time and calculation expensive
fragment reassembly algorithm by sending specially crafted packets
which could lead to a CPU saturation and hence a denial of service on
the system. (CVE-2018-5391)

* kernel: out-of-bounds access in the show_timer function in
kernel/time/ posix-timers.c (CVE-2017-18344)

* kernel: Integer overflow in udl_fb_mmap() can allow attackers to
execute code in kernel space (CVE-2018-8781)

* kernel: MIDI driver race condition leads to a double-free
(CVE-2018-10902)

* kernel: Missing check in inode_init_owner() does not clear SGID bit
on non-directories for non-members (CVE-2018-13405)

* kernel: AIO write triggers integer overflow in some protocols
(CVE-2015-8830)

* kernel: Use-after-free in snd_pcm_info function in ALSA subsystem
potentially leads to privilege escalation (CVE-2017-0861)

* kernel: Handling of might_cancel queueing is not properly pretected
against race (CVE-2017-10661)

* kernel: Salsa20 encryption algorithm does not correctly handle
zero-length inputs allowing local attackers to cause denial of service
(CVE-2017-17805)

* kernel: Inifinite loop vulnerability in madvise_willneed() function
allows local denial of service (CVE-2017-18208)

* kernel: fuse-backed file mmap-ed onto process cmdline arguments
causes denial of service (CVE-2018-1120)

* kernel: a NULL pointer dereference in dccp_write_xmit() leads to a
system crash (CVE-2018-1130)

* kernel: drivers/block/loop.c mishandles lo_release serialization
allowing denial of service (CVE-2018-5344)

* kernel: Missing length check of payload in _sctp_make_chunk()
function allows denial of service (CVE-2018-5803)

* kernel: buffer overflow in drivers/net/wireless/ath/wil6210/
wmi.c:wmi_set_ie() may lead to memory corruption (CVE-2018-5848)

* kernel: out-of-bound write in ext4_init_block_bitmap function with a
crafted ext4 image (CVE-2018-10878)

* kernel: Improper validation in bnx2x network card driver can allow
for denial of service attacks via crafted packet (CVE-2018-1000026)

* kernel: Information leak when handling NM entries containing NUL
(CVE-2016-4913)

* kernel: Mishandling mutex within libsas allowing local Denial of
Service (CVE-2017-18232)

* kernel: NULL pointer dereference in ext4_process_freed_data() when
mounting crafted ext4 image (CVE-2018-1092)

* kernel: NULL pointer dereference in ext4_xattr_inode_hash() causes
crash with crafted ext4 image (CVE-2018-1094)

* kernel: vhost: Information disclosure in
vhost/vhost.c:vhost_new_msg() (CVE-2018-1118)

* kernel: Denial of service in resv_map_release function in
mm/hugetlb.c (CVE-2018-7740)

* kernel: Memory leak in the sas_smp_get_phy_events function in
drivers/scsi/ libsas/sas_expander.c (CVE-2018-7757)

* kernel: Invalid pointer dereference in xfs_ilock_attr_map_shared()
when mounting crafted xfs image allowing denial of service
(CVE-2018-10322)

* kernel: use-after-free detected in ext4_xattr_set_entry with a
crafted file (CVE-2018-10879)

* kernel: out-of-bound access in ext4_get_group_info() when mounting
and operating a crafted ext4 image (CVE-2018-10881)

* kernel: stack-out-of-bounds write in jbd2_journal_dirty_metadata
function (CVE-2018-10883)

"Linux 4.9 has been packaged for Debian 8 as linux-4.9. This provides a
supported upgrade path for systems that currently use kernel packages
from the 'jessie-backports' suite.

There is no need to upgrade systems using Linux 3.16, as that kernel
version will also continue to be supported in the LTS period.

This backport does not include the following binary packages :

hyperv-daemons libcpupower1 libcpupower-dev libusbip-dev
linux-compiler-gcc-4.9-x86 linux-cpupower linux-libc-dev usbip

Older versions of most of those are built from other source packages
in Debian 8.

Several vulnerabilities have been discovered in the Linux kernel that
may lead to a privilege escalation, denial of service or information
leaks.

CVE-2017-5753

Further instances of code that was vulnerable to Spectre variant 1
(bounds-check bypass) have been mitigated.

CVE-2017-18255

It was discovered that the performance events subsystem did not
properly validate the value of the kernel.perf_cpu_time_max_percent
sysctl. Setting a large value could have an unspecified security
impact. However, only a privileged user can set this sysctl.

CVE-2018-1118

The syzbot software found that the vhost driver did not initialise
message buffers which would later be read by user processes. A user
with access to the /dev/vhost-net device could use this to read
sensitive information from the kernel or other users' processes.

CVE-2018-1120

Qualys reported that a user able to mount FUSE filesystems can create
a process such that when another process attempting to read its
command line will be blocked for an arbitrarily long time. This could
be used for denial of service, or to aid in exploiting a race
condition in the other program.

CVE-2018-1130

The syzbot software found that the DCCP implementation of sendmsg()
does not check the socket state, potentially leading to a NULL pointer
dereference. A local user could use this to cause a denial of service
(crash). 

CVE-2018-3639

Multiple researchers have discovered that Speculative Store Bypass
(SSB), a feature implemented in many processors, could be used to read
sensitive information from another context. In particular, code in a
software sandbox may be able to read sensitive information from
outside the sandbox. This issue is also known as Spectre variant 4.

This update allows the issue to be mitigated on some x86
processors by disabling SSB. This requires an update to the
processor's microcode, which is non-free. It may be included
in an update to the system BIOS or UEFI firmware, or in a
future update to the intel-microcode or amd64-microcode
packages.

Disabling SSB can reduce performance significantly, so by
default it is only done in tasks that use the seccomp
feature. Applications that require this mitigation should
request it explicitly through the prctl() system call. Users
can control where the mitigation is enabled with the
spec_store_bypass_disable kernel parameter.

CVE-2018-5814

Jakub Jirasek reported race conditions in the USB/IP host driver. A
malicious client could use this to cause a denial of service (crash or
memory corruption), and possibly to execute code, on a USB/IP server.

CVE-2018-10021

A physically present attacker who unplugs a SAS cable can cause a
denial of service (memory leak and WARN).

CVE-2018-10087, CVE-2018-10124

zhongjiang found that the wait4() and kill() system call
implementations did not check for the invalid pid value of INT_MIN. If
a user passed this value, the behaviour of the code was formally
undefined and might have had a security impact.

CVE-2018-10853

Andy Lutomirski and Mika Penttil&auml; reported that KVM for x86
processors did not perform a necessary privilege check when emulating
certain instructions. This could be used by an unprivileged user in a
guest VM to escalate their privileges within the guest.

CVE-2018-10876, CVE-2018-10877, CVE-2018-10878, CVE-2018-10879,
CVE-2018-10880, CVE-2018-10881, CVE-2018-10882, CVE-2018-10883

Wen Xu at SSLab, Gatech, reported that crafted ext4 filesystem images
could trigger a crash or memory corruption. A local user able to mount
arbitrary filesystems, or an attacker providing filesystems to be
mounted, could use this for denial of service or possibly for
privilege escalation.

CVE-2018-10940

Dan Carpenter reported that the optical disc driver (cdrom) does not
correctly validate the parameter to the CDROM_MEDIA_CHANGED ioctl. A
user with access to a cdrom device could use this to cause a denial of
service (crash).

CVE-2018-11506

Piotr Gabriel Kosinski and Daniel Shapira reported that the SCSI
optical disc driver (sr) did not allocate a sufficiently large buffer
for sense data. A user with access to a SCSI optical disc device that
can produce more than 64 bytes of sense data could use this to cause a
denial of service (crash or memory corruption), and possibly for
privilege escalation.

CVE-2018-12233

Shankara Pailoor reported that a crafted JFS filesystem image could
trigger a denial of service (memory corruption). This could possibly
also be used for privilege escalation.

CVE-2018-1000204

The syzbot software found that the SCSI generic driver (sg) would in
some circumstances allow reading data from uninitialised buffers,
which could include sensitive information from the kernel or other
tasks. However, only privileged users with the CAP_SYS_ADMIN or
CAP_SYS_RAWIO capability were allowed to do this, so this has little
or no security impact.

For Debian 8 'Jessie', these problems have been fixed in version
4.9.110-1~deb8u1. This update additionally fixes Debian bugs #860900,
#872907, #892057, #896775, #897590, and #898137; and includes many
more bug fixes from stable updates 4.9.89-4.9.110 inclusive.

We recommend that you upgrade your linux-4.9 packages.

    descriptionWen Xu discovered that a use-after-free vulnerability existed in the ext4 filesystem implementation in the Linux kernel. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-10876, CVE-2018-10879) Wen Xu discovered that a buffer overflow existed in the ext4 filesystem implementation in the Linux kernel. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-10877) Wen Xu discovered that an out-of-bounds write vulnerability existed in the ext4 filesystem implementation in the Linux kernel. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-10878, CVE-2018-10882) Wen Xu discovered that the ext4 filesystem implementation in the Linux kernel did not properly ensure that xattr information remained in inode bodies. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service (system crash). (CVE-2018-10880) Wen Xu discovered that the ext4 file system implementation in the Linux kernel could possibly perform an out of bounds write when updating the journal for an inline file. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service (system crash). (CVE-2018-10883) It was discovered that a race condition existed in the vsock address family implementation of the Linux kernel that could lead to a use-after-free condition. A local attacker in a guest virtual machine could use this to expose sensitive information (host machine kernel memory). (CVE-2018-14625) Cfir Cohen discovered that a use-after-free vulnerability existed in the KVM implementation of the Linux kernel, when handling interrupts in environments where nested virtualization is in use (nested KVM virtualization is not enabled by default in Ubuntu kernels). A local attacker in a guest VM could possibly use this to gain administrative privileges in a host machine. (CVE-2018-16882) Jann Horn discovered that the procfs file system implementation in the Linux kernel did not properly restrict the ability to inspect the kernel stack of an arbitrary task. A local attacker could use this to expose sensitive information. (CVE-2018-17972) Jann Horn discovered that the mremap() system call in the Linux kernel did not properly flush the TLB when completing, potentially leaving access to a physical page after it has been released to the page allocator. A local attacker could use this to cause a denial of service (system crash), expose sensitive information, or possibly execute arbitrary code. (CVE-2018-18281) Wei Wu discovered that the KVM implementation in the Linux kernel did not properly ensure that ioapics were initialized. A local attacker could use this to cause a denial of service (system crash). (CVE-2018-19407) It was discovered that the debug interface for the Linux kernel

    descriptionUSN-3871-1 fixed vulnerabilities in the Linux kernel for Ubuntu 18.04 LTS. Unfortunately, that update introduced regressions with docking station displays and mounting ext4 file systems with the meta_bg option enabled. This update fixes the problems. We apologize for the inconvenience. Original advisory details : Wen Xu discovered that a use-after-free vulnerability existed in the ext4 filesystem implementation in the Linux kernel. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-10876, CVE-2018-10879) Wen Xu discovered that a buffer overflow existed in the ext4 filesystem implementation in the Linux kernel. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-10877) Wen Xu discovered that an out-of-bounds write vulnerability existed in the ext4 filesystem implementation in the Linux kernel. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-10878, CVE-2018-10882) Wen Xu discovered that the ext4 filesystem implementation in the Linux kernel did not properly ensure that xattr information remained in inode bodies. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service (system crash). (CVE-2018-10880) Wen Xu discovered that the ext4 file system implementation in the Linux kernel could possibly perform an out of bounds write when updating the journal for an inline file. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service (system crash). (CVE-2018-10883) It was discovered that a race condition existed in the vsock address family implementation of the Linux kernel that could lead to a use-after-free condition. A local attacker in a guest virtual machine could use this to expose sensitive information (host machine kernel memory). (CVE-2018-14625) Cfir Cohen discovered that a use-after-free vulnerability existed in the KVM implementation of the Linux kernel, when handling interrupts in environments where nested virtualization is in use (nested KVM virtualization is not enabled by default in Ubuntu kernels). A local attacker in a guest VM could possibly use this to gain administrative privileges in a host machine. (CVE-2018-16882) Jann Horn discovered that the procfs file system implementation in the Linux kernel did not properly restrict the ability to inspect the kernel stack of an arbitrary task. A local attacker could use this to expose sensitive information. (CVE-2018-17972) Jann Horn discovered that the mremap() system call in the Linux kernel did not properly flush the TLB when completing, potentially leaving access to a physical page after it has been released to the page allocator. A local attacker could use this to cause a denial of service (system crash), expose sensitive information, or possibly execute arbitrary code. (CVE-2018-18281) Wei Wu discovered that the KVM implementation in the Linux kernel did not properly ensure that ioapics were initialized.

    NASL idSUSE_SU-2018-2776-1.NASL
    descriptionThe SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.155 to receive various security and bugfixes. The following security bugs were fixed : CVE-2018-13093: Prevent NULL pointer dereference and panic in lookup_slow() on a NULL inode->i_ops pointer when doing pathwalks on a corrupted xfs image. This occured because of a lack of proper validation that cached inodes are free during allocation (bnc#1100001). CVE-2018-13095: Prevent denial of service (memory corruption and BUG) that could have occurred for a corrupted xfs image upon encountering an inode that is in extent format, but has more extents than fit in the inode fork (bnc#1099999). CVE-2018-13094: Prevent OOPS that may have occured for a corrupted xfs image after xfs_da_shrink_inode() is called with a NULL bp (bnc#1100000). CVE-2018-12896: Prevent integer overflow in the POSIX timer code that was caused by the way the overrun accounting works. Depending on interval and expiry time values, the overrun can be larger than INT_MAX, but the accounting is int based. This basically made the accounting values, which are visible to user space via timer_getoverrun(2) and siginfo::si_overrun, random. This allowed a local user to cause a denial of service (signed integer overflow) via crafted mmap, futex, timer_create, and timer_settime system calls (bnc#1099922). CVE-2018-16658: Prevent information leak in cdrom_ioctl_drive_status that could have been used by local attackers to read kernel memory (bnc#1107689). CVE-2018-6555: The irda_setsockopt function allowed local users to cause a denial of service (ias_object use-after-free and system crash) or possibly have unspecified other impact via an AF_IRDA socket (bnc#1106511). CVE-2018-6554: Prevent memory leak in the irda_bind function that allowed local users to cause a denial of service (memory consumption) by repeatedly binding an AF_IRDA socket (bnc#1106509). CVE-2018-1129: A flaw was found in the way signature calculation was handled by cephx authentication protocol. An attacker having access to ceph cluster network who is able to alter the message payload was able to bypass signature checks done by cephx protocol (bnc#1096748). CVE-2018-1128: It was found that cephx authentication protocol did not verify ceph clients correctly and was vulnerable to replay attack. Any attacker having access to ceph cluster network who is able to sniff packets on network can use this vulnerability to authenticate with ceph service and perform actions allowed by ceph service (bnc#1096748). CVE-2018-10938: A crafted network packet sent remotely by an attacker forced the kernel to enter an infinite loop in the cipso_v4_optptr() function leading to a denial-of-service (bnc#1106016). CVE-2018-15572: The spectre_v2_select_mitigation function did not always fill RSB upon a context switch, which made it easier for attackers to conduct userspace-userspace spectreRSB attacks (bnc#1102517). CVE-2018-10902: Protect against concurrent access to prevent double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status(). A malicious local attacker could have used this for privilege escalation (bnc#1105322 1105323). CVE-2018-9363: Prevent buffer overflow in hidp_process_report (bsc#1105292) CVE-2018-10883: A local user could have caused an out-of-bounds write in jbd2_journal_dirty_metadata(), a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image (bsc#1099863). CVE-2018-10879: A local user could have caused a use-after-free in ext4_xattr_set_entry function and a denial of service or unspecified other impact by renaming a file in a crafted ext4 filesystem image (bsc#1099844). CVE-2018-10878: A local user could have caused an out-of-bounds write and a denial of service or unspecified other impact by mounting and operating a crafted ext4 filesystem image (bsc#1099813). CVE-2018-10876: A use-after-free was possible in ext4_ext_remove_space() function when mounting and operating a crafted ext4 image (bsc#1099811). CVE-2018-10877: Prevent out-of-bound access in the ext4_ext_drop_refs() function when operating on a crafted ext4 filesystem image (bsc#1099846). CVE-2018-10881: A local user could have caused an out-of-bound access in ext4_get_group_info function, a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image (bsc#1099864). CVE-2018-10882: A local user could have caused an out-of-bound write, a denial of service, and a system crash by unmounting a crafted ext4 filesystem image (bsc#1099849). CVE-2018-10880: Prevent stack-out-of-bounds write in the ext4 filesystem code when mounting and writing to a crafted ext4 image in ext4_update_inline_data(). An attacker could have used this to cause a system crash and a denial of service (bsc#1099845). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    descriptionThe SUSE Linux Enterprise 12 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : CVE-2018-14634: Prevent integer overflow in create_elf_tables that allowed a local attacker to exploit this vulnerability via a SUID-root binary and obtain full root privileges (bsc#1108912) CVE-2018-14617: Prevent NULL pointer dereference and panic in hfsplus_lookup() when opening a file (that is purportedly a hard link) in an hfs+ filesystem that has malformed catalog data, and is mounted read-only without a metadata directory (bsc#1102870) CVE-2018-16276: Incorrect bounds checking in the yurex USB driver in yurex_read allowed local attackers to use user access read/writes to crash the kernel or potentially escalate privileges (bsc#1106095) CVE-2018-12896: Prevent integer overflow in the POSIX timer code that was caused by the way the overrun accounting works. Depending on interval and expiry time values, the overrun can be larger than INT_MAX, but the accounting is int based. This basically made the accounting values, which are visible to user space via timer_getoverrun(2) and siginfo::si_overrun, random. This allowed a local user to cause a denial of service (signed integer overflow) via crafted mmap, futex, timer_create, and timer_settime system calls (bnc#1099922) CVE-2018-13093: Prevent NULL pointer dereference and panic in lookup_slow() on a NULL inode->i_ops pointer when doing pathwalks on a corrupted xfs image. This occured because of a lack of proper validation that cached inodes are free during allocation (bnc#1100001) CVE-2018-10940: The cdrom_ioctl_media_changed function allowed local attackers to use a incorrect bounds check in the CDROM driver CDROM_MEDIA_CHANGED ioctl to read out kernel memory (bsc#1092903) CVE-2018-16658: Prevent information leak in cdrom_ioctl_drive_status that could have been used by local attackers to read kernel memory (bnc#1107689) CVE-2018-6555: The irda_setsockopt function allowed local users to cause a denial of service (ias_object use-after-free and system crash) or possibly have unspecified other impact via an AF_IRDA socket (bnc#1106511) CVE-2018-6554: Prevent memory leak in the irda_bind function that allowed local users to cause a denial of service (memory consumption) by repeatedly binding an AF_IRDA socket (bnc#1106509) CVE-2018-10853: The KVM hypervisor did not check current privilege(CPL) level while emulating unprivileged instructions. An unprivileged guest user/process could have used this flaw to potentially escalate privileges inside guest (bsc#1097104) CVE-2018-10902: Protect against concurrent access to prevent double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status(). A malicious local attacker could have used this for privilege escalation (bnc#1105322). CVE-2018-10879: A local user could have caused a use-after-free in ext4_xattr_set_entry function and a denial of service or unspecified other impact by renaming a file in a crafted ext4 filesystem image (bsc#1099844) CVE-2018-10883: A local user could have caused an out-of-bounds write in jbd2_journal_dirty_metadata(), a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image (bsc#1099863) CVE-2018-10880: Prevent stack-out-of-bounds write in the ext4 filesystem code when mounting and writing to a crafted ext4 image in ext4_update_inline_data(). An attacker could have used this to cause a system crash and a denial of service (bsc#1099845) CVE-2018-10882: A local user could have caused an out-of-bound write, a denial of service, and a system crash by unmounting a crafted ext4 filesystem image (bsc#1099849) CVE-2018-10881: A local user could have caused an out-of-bound access in ext4_get_group_info function, a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image (bsc#1099864) CVE-2018-10877: Prevent out-of-bound access in the ext4_ext_drop_refs() function when operating on a crafted ext4 filesystem image (bsc#1099846) CVE-2018-10876: A use-after-free was possible in ext4_ext_remove_space() function when mounting and operating a crafted ext4 image (bsc#1099811) CVE-2018-10878: A local user could have caused an out-of-bounds write and a denial of service or unspecified other impact by mounting and operating a crafted ext4 filesystem image (bsc#1099813) CVE-2018-17182: An issue was discovered in the Linux kernel The vmacache_flush_all function in mm/vmacache.c mishandled sequence number overflows. An attacker can trigger a use-after-free (and possibly gain privileges) via certain thread creation, map, unmap, invalidation, and dereference operations (bnc#1108399).
