Summary

An issue was discovered in the Linux kernel before 4.20.15. The nfc_llcp_build_tlv function in net/nfc/llcp_commands.c may return NULL. If the caller does not check for this, it will trigger a NULL pointer dereference. This will cause denial of service. This affects nfc_llcp_build_gb in net/nfc/llcp_core.c.

    descriptionThe SUSE Linux Enterprise 15 kernel version 4.12.14 was updated to receive various security and bugfixes. The following security bugs were fixed : CVE-2019-10638: Attackers used to be able to track the Linux kernel by the IP ID values the kernel produces for connection-less protocols. When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). An attack could have been conducted by hosting a crafted web page that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses. [bnc#1140575] CVE-2019-10639: The Linux kernel used to allow Information Exposure (partial kernel address disclosure), leading to a KASLR bypass. Specifically, it was possible to extract the KASLR kernel image offset using the IP ID values the kernel produces for connection-less protocols. When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This key contains enough bits from a kernel address (of a static variable) so when the key was extracted (via enumeration), the offset of the kernel image was exposed. This attack could be carried out remotely by the attacker forcing the target device to send UDP or ICMP traffic to attacker-controlled IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server. ICMP traffic is trivial if the server answers ICMP Echo requests (ping). For client targets, if the target visits the attacker

"The SUSE Linux Enterprise 15 kernel version 4.12.14 was updated to
receive various security and bugfixes.

The following security bugs were fixed :

CVE-2019-10638: Attackers used to be able to track the Linux kernel by
the IP ID values the kernel produces for connection-less protocols.
When such traffic was sent to multiple destination IP addresses, it
was possible to obtain hash collisions (of indices to the counter
array) and thereby obtain the hashing key (via enumeration). An attack
could have been conducted by hosting a crafted web page that uses
WebRTC or gQUIC to force UDP traffic to attacker-controlled IP
addresses. [bnc#1140575]

CVE-2019-10639: The Linux kernel used to allow Information Exposure
(partial kernel address disclosure), leading to a KASLR bypass.
Specifically, it was possible to extract the KASLR kernel image offset
using the IP ID values the kernel produces for connection-less
protocols. When such traffic was sent to multiple destination IP
addresses, it was possible to obtain hash collisions (of indices to
the counter array) and thereby obtain the hashing key (via
enumeration). This key contains enough bits from a kernel address (of
a static variable) so when the key was extracted (via enumeration),
the offset of the kernel image was exposed. This attack could be
carried out remotely by the attacker forcing the target device to send
UDP or ICMP traffic to attacker-controlled IP addresses. Forcing a
server to send UDP traffic is trivial if the server is a DNS server.
ICMP traffic is trivial if the server answers ICMP Echo requests
(ping). For client targets, if the target visits the attacker's web
page, then WebRTC or gQUIC can be used to force UDP traffic to
attacker-controlled IP addresses. [bnc#1140577]

CVE-2018-20836: A race condition used to exist in smp_task_timedout()
and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to
a use-after-free. [bnc#1134395]

CVE-2019-10126: A heap-based buffer overflow in the wireless driver
code was fixed. This issue might have lead to memory corruption and
possibly other consequences. [bnc#1136935]

CVE-2019-11599: The coredump implementation did not use locking or
other mechanisms to prevent vma layout or vma flags changes while it
ran, which allowed local users to obtain sensitive information, cause
a denial of service, or possibly have unspecified other impact by
triggering a race condition with mmget_not_zero or get_task_mm calls.
[bnc#1131645].

CVE-2019-12614: There was an unchecked kstrdup of prop->name on
PowerPC platforms, which allowed an attacker to cause a denial of
service (NULL pointer dereference and system crash). [bnc#1137194]

CVE-2018-16871: A flaw was found in the NFS implementation. An
attacker who was able to mount an exported NFS filesystem was able to
trigger a NULL pointer dereference by an invalid NFS sequence. This
could panic the machine and deny access to the NFS server. Any
outstanding disk writes to the NFS server will were lost.
[bnc#1137103]

CVE-2019-12819: The function __mdiobus_register() used to call
put_device(), which would trigger a fixed_mdio_bus_init use-after-free
error. This would cause a denial of service. [bnc#1138291]

CVE-2019-12818: The nfc_llcp_build_tlv function in
net/nfc/llcp_commands.c may return NULL. If the caller did not check
for this, it could trigger a NULL pointer dereference. This would
cause denial of service. [bnc#1138293]

CVE-2019-12456: An issue in the MPT3COMMAND case in _ctl_ioctl_main()
allowed local users to cause a denial of service or possibly have
unspecified other impact by changing the value of ioc_number between
two kernel reads of that value, aka a 'double fetch' vulnerability.
[bsc#1136922]

CVE-2019-12380: An issue was in the EFI subsystem existed that
mishandled memory allocation failures. Note, however, that all
relevant code runs only at boot-time, before any user processes are
started. Therefore, there was no possibility for an unprivileged user
to exploit this issue. [bnc#1136598]

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

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 SUSE Linux Enterprise 12 SP1 kernel was updated to receive various
security and bugfixes.

The following security bugs were fixed :

CVE-2018-5390 aka 'SegmentSmack': A remote attacker even with
relatively low bandwidth could have caused lots of CPU usage by
triggering the worst case scenario during IP and/or TCP fragment
reassembly (bsc#1102340)

CVE-2018-7191: In the tun subsystem in the Linux kernel,
dev_get_valid_name was not called before register_netdevice. This
allowed local users to cause a denial of service (NULL pointer
dereference and panic) via an ioctl(TUNSETIFF) call with a dev name
containing a / character. (bnc#1135603)

CVE-2018-20836: A race condition in smp_task_timedout() and
smp_task_done() in drivers/scsi/libsas/sas_expander.c, could have lead
to a use-after-free. (bnc#1134395)

CVE-2019-12614: An unchecked kstrdup might have allowed an attacker to
cause denial of service (a NULL pointer dereference and system crash).
(bnc#1137194)

CVE-2019-12818: The nfc_llcp_build_tlv function in
net/nfc/llcp_commands.c may have returned NULL. If the caller did not
check for this, it would trigger a NULL pointer dereference. This
would cause denial of service. (bnc#1138293)

CVE-2019-12456: An issue in the MPT3COMMAND case in _ctl_ioctl_main()
allowed local users to cause a denial of service or possibly have
unspecified other impact by changing the value of ioc_number between
two kernel reads of that value, aka a 'double fetch' vulnerability.
(bsc#1136922)

CVE-2019-11487: An attacker could have triggered use-after-free via
page reference count overflow on slow filesystems with at least of 140
GiB of RAM available. (bnc#1133190)

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 openSUSE Leap 15.1 was updated to receive various security and bugfixes. The following security bugs were fixed : - CVE-2019-11477: A sequence of SACKs may have been crafted by a remote attacker such that one can trigger an integer overflow, leading to a kernel panic. (bsc#1137586). - CVE-2019-11478: It was possible to send a crafted sequence of SACKs which would fragment the TCP retransmission queue. A remote attacker may have been able to further exploit the fragmented queue to cause an expensive linked-list walk for subsequent SACKs received for that same TCP connection. (bsc#1137586) - CVE-2019-11479: It was possible to send a crafted sequence of SACKs which would fragment the RACK send map. A remote attacker may be able to further exploit the fragmented send map to cause an expensive linked-list walk for subsequent SACKs received for that same TCP connection. This would have resulted in excess resource consumption due to low mss values. (bsc#1137586) - CVE-2019-12819: The function __mdiobus_register() in drivers/net/phy/mdio_bus.c calls put_device(), which will trigger a fixed_mdio_bus_init use-after-free. This will cause a denial of service (bnc#1138291). - CVE-2019-12818: The nfc_llcp_build_tlv function in net/nfc/llcp_commands.c may return NULL. If the caller did not check for this, it will trigger a NULL pointer dereference. This will cause denial of service. This affects nfc_llcp_build_gb in net/nfc/llcp_core.c (bnc#1138293). - CVE-2019-12456: An issue was discovered in the MPT3COMMAND case in _ctl_ioctl_main in drivers/scsi/mpt3sas/mpt3sas_ctl.c that allowed local users to cause a denial of service or possibly have unspecified other impact by changing the value of ioc_number between two kernel reads of that value, aka a

    of fwstr, which might allow an attacker to cause a
    denial of service (NULL pointer dereference and system
    crash) (bnc#1136586).

  - CVE-2019-11487: The Linux kernel allowed page->_refcount
    reference count overflow, with resultant use-after-free
    issues, if about 140 GiB of RAM exists. This is related
    to fs/fuse/dev.c, fs/pipe.c, fs/splice.c,
    include/linux/mm.h, include/linux/pipe_fs_i.h,
    kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can

"The SUSE Linux Enterprise 12 SP3 kernel was updated to receive various
security and bugfixes.

The following security bugs were fixed :

CVE-2019-10638: In the Linux kernel, a device could be tracked by an
attacker using the IP ID values the kernel produces for
connection-less protocols (e.g., UDP and ICMP). When such traffic was
sent to multiple destination IP addresses, it was possible to obtain
hash collisions (of indices to the counter array) and thereby obtain
the hashing key (via enumeration). An attack may have been conducted
by hosting a crafted web page that uses WebRTC or gQUIC to force UDP
traffic to attacker-controlled IP addresses (bnc#1140575 1140577).

CVE-2019-10639: The Linux kernel allowed Information Exposure (partial
kernel address disclosure), that lead to a KASLR bypass. Specifically,
it was possible to extract the KASLR kernel image offset using the IP
ID values the kernel produces for connection-less protocols (e.g., UDP
and ICMP). When such traffic is sent to multiple destination IP
addresses, it was possible to obtain hash collisions (of indices to
the counter array) and thereby obtain the hashing key (via
enumeration). This key contains enough bits from a kernel address (of
a static variable) so when the key is extracted (via enumeration), the
offset of the kernel image is exposed. This attack could be carried
out remotely, by the attacker forcing the target device to send UDP or
ICMP (or certain other) traffic to attacker-controlled IP addresses.
Forcing a server to send UDP traffic is trivial if the server is a DNS
server. ICMP traffic is trivial if the server answers ICMP Echo
requests (ping). For client targets, if the target visited the
attacker's web page, then WebRTC or gQUIC could be used to force UDP
traffic to attacker-controlled IP addresses. NOTE: this attack against
KASLR became viable because IP ID generation was changed to have a
dependency on an address associated with a network namespace
(bnc#1140577).

CVE-2019-10126: A flaw was found in the Linux kernel. A heap based
buffer overflow in mwifiex_uap_parse_tail_ies function in
drivers/net/wireless/marvell/mwifiex/ie.c might have lead to memory
corruption and possibly other consequences (bnc#1136935).

CVE-2018-20836: An issue was discovered in the Linux kernel There was
a race condition in smp_task_timedout() and smp_task_done() in
drivers/scsi/libsas/sas_expander.c, leading to a use-after-free
(bnc#1134395).

CVE-2019-11599: The coredump implementation in the Linux kernel did
not use locking or other mechanisms to prevent vma layout or vma flags
changes while it ran, which allowed local users to obtain sensitive
information, cause a denial of service, or possibly have unspecified
other impact by triggering a race condition with mmget_not_zero or
get_task_mm call. This is related to fs/userfaultfd.c, mm/mmap.c,
fs/proc/task_mmu.c, and drivers/infiniband/core/uverbs_main.c
(bnc#1131645 1133738).

CVE-2019-12614: An issue was discovered in dlpar_parse_cc_property in
arch/powerpc/platforms/pseries/dlpar.c in the Linux kernel There was
an unchecked kstrdup of prop-name, which might have allowed an
attacker to cause a denial of service (NULL pointer dereference and
system crash) (bnc#1137194).

CVE-2019-12819: An issue was discovered in the Linux kernel The
function __mdiobus_register() in drivers/net/phy/mdio_bus.c calls
put_device(), which would trigger a fixed_mdio_bus_init
use-after-free. This would cause a denial of service (bnc#1138291).

CVE-2019-12818: An issue was discovered in the Linux kernel The
nfc_llcp_build_tlv function in net/nfc/llcp_commands.c may return
NULL. If the caller did not check for this, it would trigger a NULL
pointer dereference. This would cause a denial of service. This
affected nfc_llcp_build_gb in net/nfc/llcp_core.c (bnc#1138293).

CVE-2019-12456: A double-fetch bug in _ctl_ioctl_main() could lead to
a local denial of service attack (bsc#1136922 CVE-2019-12456).

CVE-2019-12380: An issue was discovered in the efi subsystem in the
Linux kernel phys_efi_set_virtual_address_map in
arch/x86/platform/efi/efi.c and efi_call_phys_prolog in
arch/x86/platform/efi/efi_64.c mishandle memory allocation failures.
NOTE: This id is disputed as not being an issue because ;All the code
touched by the referenced commit runs only at boot, before any user
processes are started. Therefore, there is no possibility for an
unprivileged user to control it (bnc#1136598).

CVE-2019-11487: The Linux kernel before allowed page-_refcount
reference count overflow, with resultant use-after-free issues, if
about 140 GiB of RAM exists. This is related to fs/fuse/dev.c,
fs/pipe.c, fs/splice.c, include/linux/mm.h, include/linux/pipe_fs_i.h,
kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It could occur with
FUSE requests (bnc#1133190 1133191).

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 openSUSE Leap 15.0 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : - CVE-2019-11477: A sequence of SACKs may have been crafted by a remote attacker such that one can trigger an integer overflow, leading to a kernel panic. (bsc#1137586). - CVE-2019-11478: It was possible to send a crafted sequence of SACKs which would fragment the TCP retransmission queue. A remote attacker may have been able to further exploit the fragmented queue to cause an expensive linked-list walk for subsequent SACKs received for that same TCP connection. (bsc#1137586) - CVE-2019-11479: It was possible to send a crafted sequence of SACKs which would fragment the RACK send map. A remote attacker may be able to further exploit the fragmented send map to cause an expensive linked-list walk for subsequent SACKs received for that same TCP connection. This would have resulted in excess resource consumption due to low mss values. (bsc#1137586) - CVE-2019-12819: The function __mdiobus_register() in drivers/net/phy/mdio_bus.c calls put_device(), which will trigger a fixed_mdio_bus_init use-after-free. This will cause a denial of service (bnc#1138291). - CVE-2019-12818: The nfc_llcp_build_tlv function in net/nfc/llcp_commands.c may return NULL. If the caller did not check for this, it will trigger a NULL pointer dereference. This will cause denial of service. This affects nfc_llcp_build_gb in net/nfc/llcp_core.c (bnc#1138293). - CVE-2019-12456: local users could cause a denial of service or possibly have unspecified other impact by changing the value of ioc_number between two kernel reads of that value, aka a

The following security bugs were fixed :

  - CVE-2019-11477: A sequence of SACKs may have been

    an integer overflow, leading to a kernel panic.
    (bsc#1137586).

    able to further exploit the fragmented queue to cause an

    (bsc#1137586)

  - CVE-2019-12819: The function __mdiobus_register() in
    drivers/net/phy/mdio_bus.c calls put_device(), which
    will trigger a fixed_mdio_bus_init use-after-free. This
    will cause a denial of service (bnc#1138291).

  - CVE-2019-12818: The nfc_llcp_build_tlv function in
    net/nfc/llcp_commands.c may return NULL. If the caller
    did not check for this, it will trigger a NULL pointer
    dereference. This will cause denial of service. This
    affects nfc_llcp_build_gb in net/nfc/llcp_core.c
    (bnc#1138293).

  - CVE-2019-12456: local users could cause a denial of
    service or possibly have unspecified other impact by
    changing the value of ioc_number between two kernel
    reads of that value, aka a 'double fetch' vulnerability.
    (bnc#1136922)

  - CVE-2019-12380: phys_efi_set_virtual_address_map in
    arch/x86/platform/efi/efi.c and efi_call_phys_prolog in
    arch/x86/platform/efi/efi_64.c mishandle memory
    allocation failures (bnc#1136598).

  - CVE-2019-3846: A flaw that allowed an attacker to
    corrupt memory and possibly escalate privileges was
    found in the mwifiex kernel module while connecting to a
    malicious wireless network (bnc#1136424).

  - CVE-2019-10124: An attacker could exploit an issue in
    the hwpoison implementation to cause a denial of service
    (BUG). (bsc#1130699)

  - CVE-2019-12382: An issue was discovered in
    drm_load_edid_firmware in
    drivers/gpu/drm/drm_edid_load.c. There was an unchecked
    kstrdup of fwstr, which might allow an attacker to cause
    a denial of service (NULL pointer dereference and system
    crash) (bnc#1136586).

  - CVE-2019-11487: The Linux kernel before 5.1-rc5 allowed
    page->_refcount reference count overflow, with resultant
    use-after-free issues, if about 140 GiB of RAM exists.
    This is related to fs/fuse/dev.c, fs/pipe.c,
    fs/splice.c, include/linux/mm.h,
    include/linux/pipe_fs_i.h, kernel/trace/trace.c,
    mm/gup.c, and mm/hugetlb.c. It can occur with FUSE
    requests (bnc#1133190).

  - CVE-2019-5489: The mincore() implementation in
    mm/mincore.c allowed local attackers to observe page
    cache access patterns of other processes on the same
    system, potentially allowing sniffing of secret
    information. (Fixing this affects the output of the
    fincore program.) Limited remote exploitation may be
    possible, as demonstrated by latency differences in
    accessing public files from an Apache HTTP Server
    (bnc#1120843).

  - CVE-2019-11833: fs/ext4/extents.c did not zero out the
    unused memory region in the extent tree block, which
    might allow local users to obtain sensitive information
    by reading uninitialized data in the filesystem
    (bnc#1135281).

  - CVE-2018-7191: In the tun subsystem dev_get_valid_name
    is not called before register_netdevice. This allowed
    local users to cause a denial of service (NULL pointer
    dereference and panic) via an ioctl(TUNSETIFF) call with
    a dev name containing a / character. This is similar to
    CVE-2013-4343 (bnc#1135603).

  - CVE-2019-11085: Insufficient input validation in Kernel
    Mode Driver in Intel(R) i915 Graphics may have allowed
    an authenticated user to potentially enable escalation
    of privilege via local access (bnc#1135278).

The following non-security bugs were fixed :

  - 9p locks: add mount option for lock retry interval
    (bsc#1051510).

    exists in the functions
    ath6kl_wmi_pstream_timeout_event_rx and
    ath6kl_wmi_cac_event_rx in the file
    driverset/wireless/ath/ath6kl/wmi.c.(CVE-2019-15926)An
    issue was discovered in the Linux kernel before 5.0.6.
    There is a memory leak issue when idr_alloc() fails in
    genl_register_family() in
    netetlink/genetlink.c.(CVE-2019-15921)An issue was
    discovered in the Linux kernel before 4.20.2. An
    out-of-bounds access exists in the function
    build_audio_procunit in the file
    sound/usb/mixer.c.(CVE-2019-15927)An issue was
    discovered in the Linux kernel before 5.0.9. There is a
    use-after-free in atalk_proc_exit, related to
    net/appletalk/atalk_proc.c, net/appletalk/ddp.c, and
    net/appletalk/sysctl_net_atalk.c.(CVE-2019-15292)An
    issue was discovered in fs/xfs/xfs_super.c in the Linux
    kernel before 4.18. A use after free exists, related to
    xfs_fs_fill_super failure.(CVE-2018-20976)In the Linux
    kernel before 5.1.13, there is a memory leak in
    drivers/scsi/libsas/sas_expander.c when SAS expander
    discovery fails. This will cause a BUG and denial of
    service.(CVE-2019-15807)A vulnerability was found in
    Linux kernel's, versions up to 3.10, implementation of
    overlayfs. An attacker with local access can create a
    denial of service situation via NULL pointer
    dereference in ovl_posix_acl_create function in
    fs/overlayfs/dir.c. This can allow attackers with
    ability to create directories on overlayfs to crash the
    kernel creating a denial of service
    (DOS).(CVE-2019-10140)In the Linux kernel, a certain
    net/ipv4/tcp_output.c change, which was properly
    incorporated into 4.16.12, was incorrectly backported
    to the earlier longterm kernels, introducing a new
    vulnerability that was potentially more severe than the
    issue that was intended to be fixed by backporting.
    Specifically, by adding to a write queue between
    disconnection and re-connection, a local attacker can
    trigger multiple use-after-free conditions. This can
    result in a kernel crash, or potentially in privilege
    escalation.(CVE-2019-15239)check_input_term in
    sound/usb/mixer.c in the Linux kernel through 5.2.9
    mishandles recursion, leading to kernel stack
    exhaustion.(CVE-2019-15118)drivers
    et/wireless/ath/ath10k/usb.c in the Linux kernel
    through 5.2.8 has a NULL pointer dereference via an
    incomplete address in an endpoint
    descriptor.(CVE-2019-15099)drivers
    et/wireless/ath/ath6kl/usb.c in the Linux kernel
    through 5.2.9 has a NULL pointer dereference via an
    incomplete address in an endpoint
    descriptor.(CVE-2019-15098)A flaw was found in the
    Linux kernel's Bluetooth implementation of UART. An
    attacker with local access and write permissions to the
    Bluetooth hardware could use this flaw to issue a
    specially crafted ioctl function call and cause the
    system to crash.(CVE-2019-10207)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. Ceph branches
    master, mimic, luminous and jewel are believed to be
    vulnerable.(CVE-2018-1128)ax25_create in
    net/ax25/af_ax25.c in the AF_AX25 network module in the
    Linux kernel through 5.3.2 does not enforce
    CAP_NET_RAW, which means that unprivileged users can
    create a raw socket, aka
    CID-0614e2b73768.(CVE-2019-17052)ieee802154_create in
    net/ieee802154/socket.c in the AF_IEEE802154 network
    module in the Linux kernel through 5.3.2 does not
    enforce CAP_NET_RAW, which means that unprivileged
    users can create a raw socket, aka
    CID-e69dbd4619e7.(CVE-2019-17053)atalk_create in
    net/appletalk/ddp.c in the AF_APPLETALK network module
    in the Linux kernel through 5.3.2 does not enforce
    CAP_NET_RAW, which means that unprivileged users can
    create a raw socket, aka
    CID-6cc03e8aa36c.(CVE-2019-17054)base_sock_create in
    drivers/isdn/mISDN/socket.c in the AF_ISDN network
    module in the Linux kernel through 5.3.2 does not
    enforce CAP_NET_RAW, which means that unprivileged
    users can create a raw socket, aka
    CID-b91ee4aa2a21.(CVE-2019-17055)llcp_sock_create in
    net fc/llcp_sock.c in the AF_NFC network module in the
    Linux kernel through 5.3.2 does not enforce
    CAP_NET_RAW, which means that unprivileged users can
    create a raw socket, aka
    CID-3a359798b176.(CVE-2019-17056)A flaw was found in
    the Linux kernel's freescale hypervisor manager
    implementation, kernel versions 5.0.x up to, excluding
    5.0.17. A parameter passed to an ioctl was incorrectly
    validated and used in size calculations for the page
    size calculation. An attacker can use this flaw to
    crash the system, corrupt memory, or create other
    adverse security
    affects.(CVE-2019-10142)drivers/media/usb/dvb-usb/techn
    isat-usb2.c in the Linux kernel through 5.2.9 has an
    out-of-bounds read via crafted USB device traffic
    (which may be remote via usbip or
    usbredir).(CVE-2019-15505)An issue was discovered in
    the Linux kernel before 5.0.4. The 9p filesystem did
    not protect i_size_write() properly, which causes an
    i_size_read() infinite loop and denial of service on
    SMP systems.(CVE-2019-16413)An issue was discovered in
    xfs_setattr_nonsize in fs/xfs/xfs_iops.c in the Linux
    kernel through 5.2.9. XFS partially wedges when a chgrp
    fails on account of being out of disk quota.
    xfs_setattr_nonsize is failing to unlock the ILOCK
    after the xfs_qm_vop_chown_reserve call fails. This is
    primarily a local DoS attack vector, but it might
    result as well in remote DoS if the XFS filesystem is
    exported for instance via NFS.(CVE-2019-15538)A buffer
    overflow flaw was found, in versions from 2.6.34 to
    5.2.x, in the way Linux kernel's vhost functionality
    that translates virtqueue buffers to IOVs, logged the
    buffer descriptors during migration. A privileged guest
    user able to pass descriptors with invalid length to
    the host when migration is underway, could use this
    flaw to increase their privileges on the
    host.(CVE-2019-14835)An out-of-bounds access issue was
    found in the Linux kernel, all versions through 5.3, in
    the way Linux kernel's KVM hypervisor implements the
    Coalesced MMIO write operation. It operates on an MMIO
    ring buffer 'struct kvm_coalesced_mmio' object, wherein
    write indices 'ring->first' and 'ring->last' value
    could be supplied by a host user-space process. An
    unprivileged host user or process with access to
    '/dev/kvm' device could use this flaw to crash the host
    kernel, resulting in a denial of service or potentially
    escalating privileges on the system.(CVE-2019-14821)An
    information disclosure vulnerability exists when
    certain central processing units (CPU) speculatively
    access memory, aka 'Windows Kernel Information
    Disclosure Vulnerability'.
    (CVE-2019-1125)drivers/scsi/qla2xxx/qla_os.c in the
    Linux kernel 5.2.14 does not check the alloc_workqueue
    return value, leading to a NULL pointer
    dereference.(CVE-2019-16233)An issue was discovered in
    the Linux kernel before 5.0.11. fm10k_init_module in
    drivers et/ethernet/intel/fm10k/fm10k_main.c has a NULL
    pointer dereference because there is no -ENOMEM upon an
    alloc_workqueue failure.(CVE-2019-15924)An issue was
    discovered in the Linux kernel before 5.2.1. There is a
    use-after-free caused by a malicious USB device in the
    drivers et/wireless/intersil/p54/p54usb.c
    driver.(CVE-2019-15220 )In the Linux kernel before
    5.1.7, a device can be tracked by an attacker using the
    IP ID values the kernel produces for connection-less
    protocols (e.g., UDP and ICMP). When such traffic is
    sent to multiple destination IP addresses, it is
    possible to obtain hash collisions (of indices to the
    counter array) and thereby obtain the hashing key (via
    enumeration). An attack may be conducted by hosting a
    crafted web page that uses WebRTC or gQUIC to force UDP
    traffic to attacker-controlled IP
    addresses.(CVE-2019-10638)There is heap-based buffer
    overflow in Linux kernel, all versions up to, excluding
    5.3, in the marvell wifi chip driver in Linux kernel,
    that allows local users to cause a denial of
    service(system crash) or possibly execute arbitrary
    code.( CVE-2019-14814)** RESERVED ** This candidate has
    been reserved by an organization or individual that
    will use it when announcing a new security problem.
    When the candidate has been publicized, the details for
    this candidate will be provided.( CVE-2019-14815)There
    is heap-based buffer overflow in kernel, all versions
    up to, excluding 5.3, in the marvell wifi chip driver
    in Linux kernel, that allows local users to cause a
    denial of service(system crash) or possibly execute
    arbitrary code.( CVE-2019-14816)A flaw was found in the
    way Linux kernel KVM hypervisor emulated instructions
    such as sgdt/sidt/fxsave/fxrstor. It did not check
    current privilege(CPL) level while emulating
    unprivileged instructions. An unprivileged guest
    user/process could use this flaw to potentially
    escalate privileges inside guest.(CVE-2018-10853)A NULL
    pointer dereference was found in the net/rds/rdma.c
    __rds_rdma_map() function in the Linux kernel before
    4.14.7 allowing local attackers to cause a system panic
    and a denial-of-service, related to RDS_GET_MR and
    RDS_GET_MR_FOR_DEST.(CVE-2018-7492)An issue was
    discovered in the Linux kernel before 4.20.15. The
    nfc_llcp_build_tlv function in net fc/llcp_commands.c
    may return NULL. If the caller does not check for this,
    it will trigger a NULL pointer dereference. This will
    cause denial of service. This affects nfc_llcp_build_gb
    in netfc/llcp_core.c.(CVE-2019-12818)An issue was
    discovered in the Linux kernel before 5.1.8. There is a
    NULL pointer dereference caused by a malicious USB
    device in the drivers/media/usb/siano/smsusb.c
    driver.(CVE-2019-15218)An issue was discovered in the
    Linux kernel before 5.1.8. There is a NULL pointer
    dereference caused by a malicious USB device in the
    drivers/usb/misc/sisusbvga/sisusb.c
    driver.(CVE-2019-15219)An issue was discovered in the
    Linux kernel before 5.1.17. There is a NULL pointer
    dereference caused by a malicious USB device in the
    sound/usb/line6/pcm.c driver.(CVE-2019-15221)

    descriptionExample: The openSUSE Leap 42.3 kernel was updated to 4.4.180 to receive various security and bugfixes. The following security bugs were fixed : - CVE-2019-11477: A sequence of SACKs may have been crafted by a remote attacker such that one can trigger an integer overflow, leading to a kernel panic. (bsc#1137586). - CVE-2019-11478: It was possible to send a crafted sequence of SACKs which would fragment the TCP retransmission queue. A remote attacker may have been able to further exploit the fragmented queue to cause an expensive linked-list walk for subsequent SACKs received for that same TCP connection. (bsc#1137586) - CVE-2019-11479: It was possible to send a crafted sequence of SACKs which would fragment the RACK send map. A remote attacker may be able to further exploit the fragmented send map to cause an expensive linked-list walk for subsequent SACKs received for that same TCP connection. This would have resulted in excess resource consumption due to low mss values. (bsc#1137586) - CVE-2019-12819: The function __mdiobus_register() in drivers/net/phy/mdio_bus.c calls put_device(), which will trigger a fixed_mdio_bus_init use-after-free.

    descriptionThe SUSE Linux Enterprise 15 SP1 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : CVE-2019-12819: The function __mdiobus_register() called put_device(), which triggered a fixed_mdio_bus_init use-after-free. This would cause a denial of service. (bsc#1138291) CVE-2019-12818: The nfc_llcp_build_tlv function in net/nfc/llcp_commands.c may return NULL. If the caller does not check for this, it will trigger a NULL pointer dereference. This will cause denial of service. This used to affect nfc_llcp_build_gb in net/nfc/llcp_core.c. (bsc#1138293) CVE-2019-11477: A sequence of SACKs may have been crafted such that one can trigger an integer overflow, leading to a kernel panic. CVE-2019-11478: It was possible to send a crafted sequence of SACKs which will fragment the TCP retransmission queue. An attacker may have been able to further exploit the fragmented queue to cause an expensive linked-list walk for subsequent SACKs received for that same TCP connection. CVE-2019-11479: An attacker could force the Linux kernel to segment its responses into multiple TCP segments. This would drastically increased the bandwidth required to deliver the same amount of data. Further, it would consume additional resources such as CPU and NIC processing power. CVE-2019-3846: A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the mwifiex kernel module while connecting to a malicious wireless network. (bsc#1136424) CVE-2019-10124: An issue was discovered in the hwpoison implementation in mm/memory-failure.c in the Linux kernel. When soft_offline_in_use_page() runs on a thp tail page after pmd is split, an attacker could cause a denial of service (bsc#1130699, CVE-2019-10124). CVE-2019-12382: An issue was discovered in drm_load_edid_firmware in drivers/gpu/drm/drm_edid_load.c in the Linux kernel There was an unchecked kstrdup of fwstr, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash). (bsc#1136586) CVE-2019-11487: The Linux kernel allowed page reference count overflow, with resultant use-after-free issues, if about 140 GiB of RAM exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c, include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It could occur with FUSE requests. (bbsc#1133190) CVE-2019-5489: The mincore() implementation in mm/mincore.c in the Linux kernel allowed local attackers to observe page cache access patterns of other processes on the same system, potentially allowing sniffing of secret information. (Fixing this affects the output of the fincore program.) Limited remote exploitation may be possible, as demonstrated by latency differences in accessing public files from an Apache HTTP Server. (bsc#1120843) CVE-2019-11833: fs/ext4/extents.c in the Linux kernel did not zero out the unused memory region in the extent tree block, which might allow local users to obtain sensitive information by reading uninitialized data in the filesystem. (bsc#1135281) CVE-2019-11091: Microarchitectural Data Sampling Uncacheable Memory (MDSUM): Uncacheable memory on some microprocessors utilizing speculative execution may have allowed an authenticated user to potentially enable information disclosure via a side channel with local access.

    descriptionThe SUSE Linux Enterprise 12 SP 2 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : CVE-2019-10638: In the Linux kernel, a device could be tracked by an attacker using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). An attack may be conducted by hosting a crafted web page that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses. (bnc#1140575) CVE-2019-10639: The Linux kernel allowed Information Exposure (partial kernel address disclosure), leading to a KASLR bypass. Specifically, it was possible to extract the KASLR kernel image offset using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This key contains enough bits from a kernel address (of a static variable) so when the key was extracted (via enumeration), the offset of the kernel image is exposed. This attack can be carried out remotely, by the attacker forcing the target device to send UDP or ICMP (or certain other) traffic to attacker-controlled IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server. ICMP traffic is trivial if the server answers ICMP Echo requests (ping).

By setting a specific socket option, an attacker can control a pointer in kernel land and cause an inet_csk_listen_stop general protection fault, or potentially execute arbitrary code under certain circumstances. The issue can be triggered as root (e.g., inside a default LXC container or with the CAP_NET_ADMIN capability) or after namespace unsharing. This occurs because sk_type and protocol are not checked in the appropriate part of the ip6_mroute_* functions. NOTE: this affects Linux distributions that use 4.9.x longterm kernels before 4.9.187.(CVE-2017-18509)An issue was discovered in drivers/i2c/i2c-core-smbus.c in the Linux kernel before 4.14.15. There is an out of bounds write in the function i2c_smbus_xfer_emulated.(CVE-2017-18551)An issue was discovered in the Linux kernel before 4.14.11. A double free may be caused by the function allocate_trace_buffer in the file kernel/trace/trace.c.(CVE-2017-18595)The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel through 4.10.5 does not check for a zero value of certain levels data, which allows local users to cause a denial of service (ZERO_SIZE_PTR dereference, and GPF and possibly panic) via a crafted ioctl call for a /dev/dri/renderD* device.(CVE-2017-7261)The KEYS subsystem in the Linux kernel before 4.10.13 allows local users to cause a denial of service (memory consumption) via a series of KEY_REQKEY_DEFL_THREAD_KEYRING keyctl_set_reqkey_keyring calls.(CVE-2017-7472)The kernel_wait4 function in kernel/exit.c in the Linux kernel before 4.13, when an unspecified architecture and compiler is used, might allow local users to cause a denial of service by triggering an attempted use of the -INT_MIN value.(CVE-2018-10087)The kill_something_info function in kernel/signal.c in the Linux kernel before 4.13, when an unspecified architecture and compiler is used, might allow local users to cause a denial of service via an INT_MIN argument.(CVE-2018-10124)The xfs_dinode_verify function in fs/xfs/libxfs/xfs_inode_buf.c in the Linux kernel through 4.16.3 allows local users to cause a denial of service (xfs_ilock_attr_map_shared invalid pointer dereference) via a crafted xfs image.(CVE-2018-10322)The xfs_bmap_extents_to_btree function in fs/xfs/libxfs/xfs_bmap.c in the Linux kernel through 4.16.3 allows local users to cause a denial of service (xfs_bmapi_write NULL pointer dereference) via a crafted xfs image.(CVE-2018-10323)The do_get_mempolicy function in mm/mempolicy.c in the Linux kernel before 4.12.9 allows local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via crafted system calls.(CVE-2018-10675)Linux kernel is vulnerable to a 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 use this to cause a system crash and a denial of service.(CVE-2018-10880)An issue was discovered in the Linux kernel through 4.17.3. An Integer Overflow in kernel/time/posix-timers.c in the POSIX timer code is 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 makes the accounting values, which are visible to user space via timer_getoverrun(2) and siginfo::si_overrun, random. For example, a local user can cause a denial of service (signed integer overflow) via crafted mmap, futex, timer_create, and timer_settime system calls.(CVE-2018-12896)An issue was discovered in the proc_pid_stack function in fs/proc/base.c in the Linux kernel through 4.18.11. It does not ensure that only root may inspect the kernel stack of an arbitrary task, allowing a local attacker to exploit racy stack unwinding and leak kernel task stack contents.(CVE-2018-17972)An issue was discovered in the Linux kernel through 4.19. An information leak in cdrom_ioctl_select_disc in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 and CVE-2018-16658.(CVE-2018-18710 )An issue was discovered in the Linux kernel before 4.18.11. The ipddp_ioctl function in drivers et/appletalk/ipddp.c allows local users to obtain sensitive kernel address information by leveraging CAP_NET_ADMIN to read the ipddp_route dev and next fields via an SIOCFINDIPDDPRT ioctl call.(CVE-2018-20511)An issue was discovered in the Linux kernel before 4.18.7. In block/blk-core.c, there is an __blk_drain_queue() use-after-free because a certain error case is mishandled.(CVE-2018-20856)An issue was discovered in fs/xfs/xfs_super.c in the Linux kernel before 4.18. A use after free exists, related to xfs_fs_fill_super failure.(CVE-2018-20976)Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a speculative buffer overflow and side-channel analysis.(CVE-2018-3693)In the function sbusfb_ioctl_helper() in drivers/video/fbdev/sbuslib.c in the Linux kernel through 4.15, an integer signedness error allows arbitrary information leakage for the FBIOPUTCMAP_SPARC and FBIOGETCMAP_SPARC commands.(CVE-2018-6412)In nfc_llcp_build_sdreq_tlv of llcp_commands.c, there is a possible out of bounds write due to a missing bounds check.

    NASL idSUSE_SU-2019-1851-1.NASL
    descriptionThe SUSE Linux Enterprise 12 SP4 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : CVE-2019-10638: A device could have been tracked by an attacker using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). An attack may have been conducted by hosting a crafted web page that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses. (bnc#1140575) CVE-2019-10639: Information Exposure (partial kernel address disclosure), leading to a KASLR bypass. Specifically, it was possible to extract the KASLR kernel image offset using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This key contains enough bits from a kernel address (of a static variable) so when the key is extracted (via enumeration), the offset of the kernel image was exposed. This attack could have been carried out remotely, by the attacker forcing the target device to send UDP or ICMP (or certain other) traffic to attacker-controlled IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server. ICMP traffic was trivial if the server answered ICMP Echo requests (ping). For client targets, if the target visited the attacker
