It was discovered that the Siano USB MDTV receiver device driver in
the Linux kernel made improper assumptions about the device
characteristics. A physically proximate attacker could use this cause
a denial of service (system crash). (CVE-2019-15218)

It was discovered that the Line 6 POD USB device driver in the Linux
kernel did not properly validate data size information from the
device. A physically proximate attacker could use this to cause a
denial of service (system crash). (CVE-2019-15221)

Muyu Yu discovered that the CAN implementation in the Linux kernel in
some situations did not properly restrict the field size when
processing outgoing frames. A local attacker with CAP_NET_ADMIN
privileges could use this to execute arbitrary code. (CVE-2019-3701)

Vladis Dronov discovered that the debug interface for the Linux
kernel's HID subsystem did not properly validate passed parameters in
some situations. A local privileged attacker could use this to cause a
denial of service (infinite loop). (CVE-2019-3819).

The cephx authentication protocol used by Ceph was susceptible to
replay attacks, and calculated signatures incorrectly. These
vulnerabilities in the server required changes to authentication that
are incompatible with existing clients. The kernel's client code has
now been updated to be compatible with the fixed server.

CVE-2018-3639 (SSB)

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 adds a further mitigation for this issue in the
eBPF (Extended Berkeley Packet Filter) implementation.

CVE-2018-5391 (FragmentSmack)

Juha-Matti Tilli discovered a flaw in the way the Linux kernel handled
reassembly of fragmented IPv4 and IPv6 packets. A remote attacker can
take advantage of this flaw to trigger time and calculation expensive
fragment reassembly algorithms by sending specially crafted packets,
leading to remote denial of service.

This was previously mitigated by reducing the default limits
on memory usage for incomplete fragmented packets. This
update replaces that mitigation with a more complete fix.

CVE-2018-5848

The wil6210 wifi driver did not properly validate lengths in scan and
connection requests, leading to a possible buffer overflow. On systems
using this driver, a local user with the CAP_NET_ADMIN capability
could use this for denial of service (memory corruption or crash) or
potentially for privilege escalation.

CVE-2018-12896, CVE-2018-13053

Team OWL337 reported possible integer overflows in the POSIX timer
implementation. These might have some security impact.

CVE-2018-13096, CVE-2018-13097, CVE-2018-13100, CVE-2018-14614,
CVE-2018-14616

Wen Xu from SSLab at Gatech reported that crafted F2FS volumes could
trigger a crash (BUG, Oops, or division by zero) and/or out-of-bounds
memory access. An attacker able to mount such a volume could use this
to cause a denial of service or possibly for privilege escalation.

CVE-2018-13406

Dr Silvio Cesare of InfoSect reported a potential integer overflow in
the uvesafb driver. A user with permission to access such a device
might be able to use this for denial of service or privilege
escalation.

CVE-2018-14610, CVE-2018-14611, CVE-2018-14612, CVE-2018-14613

Wen Xu from SSLab at Gatech reported that crafted Btrfs volumes could
trigger a crash (Oops) and/or out-of-bounds memory access. An attacker
able to mount such a volume could use this to cause a denial of
service or possibly for privilege escalation.

CVE-2018-15471 ((XSA-270)

Felix Wilhelm of Google Project Zero discovered a flaw in the hash
handling of the xen-netback Linux kernel module. A malicious or buggy
frontend may cause the (usually privileged) backend to make out of
bounds memory accesses, potentially resulting in privilege escalation,
denial of service, or information leaks.

https://xenbits.xen.org/xsa/advisory-270.html

CVE-2018-16862

Vasily Averin and Pavel Tikhomirov from Virtuozzo Kernel Team
discovered that the cleancache memory management feature did not
invalidate cached data for deleted files. On Xen guests using the tmem
driver, local users could potentially read data from other users'
deleted files if they were able to create new files on the same
volume.

CVE-2018-17972

Jann Horn reported that the /proc/*/stack files in procfs leaked
sensitive data from the kernel. These files are now only readable by
users with the CAP_SYS_ADMIN capability (usually only root)

CVE-2018-18281

Jann Horn reported a race condition in the virtual memory manager that
can result in a process briefly having access to memory after it is
freed and reallocated. A local user could possibly exploit this for
denial of service (memory corruption) or for privilege escalation.

CVE-2018-18690

Kanda Motohiro reported that XFS did not correctly handle some xattr
(extended attribute) writes that require changing the disk format of
the xattr. A user with access to an XFS volume could use this for
denial of service.

CVE-2018-18710

It was discovered that the cdrom driver does not correctly validate
the parameter to the CDROM_SELECT_DISC ioctl. A user with access to a
cdrom device could use this to read sensitive information from the
kernel or to cause a denial of service (crash).

CVE-2018-19407

Wei Wu reported a potential crash (Oops) in the KVM implementation for
x86 processors. A user with access to /dev/kvm could use this for
denial of service.

For Debian 8 'Jessie', these problems have been fixed in version
4.9.144-3.1~deb8u1. This version also includes fixes for Debian bugs
#890034, #896911, #907581, #915229, and #915231; and other fixes
included in upstream stable updates.

We recommend that you upgrade your linux-4.9 packages.

updates.");
  script_set_attribute(attribute:"description", value:
"According to the versions of the kernel packages installed, the
EulerOS Virtualization for ARM 64 installation on the remote host is
affected by the following vulnerabilities :

  - The IPv6 SCTP implementation in net/sctp/ipv6.c in the
    Linux kernel through 3.11.1 uses data structures and
    function calls that do not trigger an intended
    configuration of IPsec encryption, which allows remote
    attackers to obtain sensitive information by sniffing
    the network.(CVE-2013-4350i1/4%0

  - The sg_ioctl function in drivers/scsi/sg.c in the Linux
    kernel allows local users to cause a denial of service
    (stack-based buffer overflow) or possibly have
    unspecified other impacts via a large command size in
    an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds
    write access in the sg_write function.(CVE-2017-7187i1/4%0

  - An issue was discovered in can_can_gw_rcv in
    net/can/gw.c in the Linux kernel through 4.19.13. The
    CAN frame modification rules allow bitwise logical
    operations that can be also applied to the can_dlc
    field. Because of a missing check, the CAN drivers may
    write arbitrary content beyond the data registers in
    the CAN controller's I/O memory when processing can-gw
    manipulated outgoing frames. This is related to
    cgw_csum_xor_rel. An unprivileged user can trigger a
    system crash (general protection
    fault).(CVE-2019-3701i1/4%0

  - net/rds/sysctl.c in the Linux kernel before 3.19 uses
    an incorrect data type in a sysctl table, which allows
    local users to obtain potentially sensitive information
    from kernel memory or possibly have unspecified other
    impact by accessing a sysctl entry.(CVE-2015-2042i1/4%0

  - The inet_csk_clone_lock function in
    net/ipv4/inet_connection_sock.c in the Linux kernel
    allows attackers to cause a denial of service (double
    free) or possibly have unspecified other impact by
    leveraging use of the accept system call. An
    unprivileged local user could use this flaw to induce
    kernel memory corruption on the system, leading to a
    crash. Due to the nature of the flaw, privilege
    escalation cannot be fully ruled out, although we
    believe it is unlikely.(CVE-2017-8890i1/4%0

  - The overlayfs implementation in the linux (aka Linux
    kernel) package before 3.19.0-21.21 in Ubuntu through
    15.04 does not properly check permissions for file
    creation in the upper filesystem directory, which
    allows local users to obtain root access by leveraging
    a configuration in which overlayfs is permitted in an
    arbitrary mount namespace.(CVE-2015-1328i1/4%0

  - 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-2018-10322i1/4%0

  - In the flush_tmregs_to_thread function in
    arch/powerpc/kernel/ptrace.c in the Linux kernel before
    4.13.5, a guest kernel crash can be triggered from
    unprivileged userspace during a core dump on a POWER
    host due to a missing processor feature check and an
    erroneous use of transactional memory (TM) instructions
    in the core dump path, leading to a denial of
    service.(CVE-2018-1091i1/4%0

  - ** DISPUTED ** drivers/scsi/libsas/sas_scsi_host.c in
    the Linux kernel before 4.16 allows local users to
    cause a denial of service (ata qc leak) by triggering
    certain failure conditions. NOTE: a third party
    disputes the relevance of this report because the
    failure can only occur for physically proximate
    attackers who unplug SAS Host Bus Adapter
    cables.(CVE-2018-10021i1/4%0

  - A use-after-free flaw was discovered in the Linux
    kernel's tty subsystem, which allows for the disclosure
    of uncontrolled memory location and possible kernel
    panic. The information leak is caused by a race
    condition when attempting to set and read the tty line
    discipline. A local attacker could use the TIOCSETD
    (via tty_set_ldisc ) to switch to a new line discipline
    a concurrent call to a TIOCGETD ioctl performing a read
    on a given tty could then access previously allocated
    memory. Up to 4 bytes could be leaked when querying the
    line discipline or the kernel could panic with a
    NULL-pointer dereference.(CVE-2016-0723i1/4%0

  - An out-of-bounds read flaw was found in the way the
    Logitech Unifying receiver driver handled HID reports
    with an invalid device_index value. An attacker with
    physical access to the system could use this flaw to
    crash the system or, potentially, escalate their
    privileges on the system.(CVE-2014-3182i1/4%0

  - arch/x86/kvm/emulate.c in the Linux kernel through
    4.9.3 allows local users to obtain sensitive
    information from kernel memory or cause a denial of
    service (use-after-free) via a crafted application that
    leverages instruction emulation for fxrstor, fxsave,
    sgdt, and sidt.(CVE-2017-2584i1/4%0

  - A flaw was found in the way the Linux kernel handled
    IRET faults during the processing of NMIs. An
    unprivileged, local user could use this flaw to crash
    the system or, potentially (although highly unlikely),
    escalate their privileges on the
    system.(CVE-2015-5157i1/4%0

  - drivers/media/media-device.c in the Linux kernel before
    3.11, as used in Android before 2016-08-05 on Nexus 5
    and 7 (2013) devices, does not properly initialize
    certain data structures, which allows local users to
    obtain sensitive information via a crafted application,
    aka Android internal bug 28750150 and Qualcomm internal
    bug CR570757, a different vulnerability than
    CVE-2014-1739.(CVE-2014-9895i1/4%0

  - A use-after-free vulnerability in sys_ioprio_get() was
    found due to get_task_ioprio() accessing the
    task-i1/4zio_context without holding the task lock and
    could potentially race with exit_io_context(), leading
    to a use-after-free.(CVE-2016-7911i1/4%0

  - A flaw was found in the Linux kernel which is related
    to the user namespace lazily unmounting file systems.
    The fs_pin struct has two members (m_list and s_list)
    which are usually initialized on use in the
    pin_insert_group function. However, these members might
    go unmodified in this case, the system panics when it
    attempts to destroy or free them. This flaw could be
    used to launch a denial-of-service
    attack.(CVE-2015-4178i1/4%0

  - A flaw was found in the Linux kernel's implementation
    of raw_sendmsg allowing a local attacker to panic the
    kernel or possibly leak kernel addresses. A local
    attacker, with the privilege of creating raw sockets,
    can abuse a possible race condition when setting the
    socket option to allow the kernel to automatically
    create ip header values and thus potentially escalate
    their privileges.(CVE-2017-17712i1/4%0

  - A flaw was discovered in the F2FS filesystem code in
    fs/f2fs/super.c in the Linux kernel. A denial of
    service, due to an out-of-bounds memory access, can
    occur upon encountering an abnormal bitmap size when
    mounting a crafted f2fs image.(CVE-2018-13096i1/4%0

  - A NULL pointer dereference flaw was found in the way
    the Linux kernel's madvise MADV_WILLNEED functionality
    handled page table locking. A local, unprivileged user
    could use this flaw to crash the
    system.(CVE-2014-8173i1/4%0

  - An out-of-bounds heap memory access leading to a Denial
    of Service, heap disclosure, or further impact was
    found in setsockopt(). The function call is normally
    restricted to root, however some processes with
    cap_sys_admin may also be able to trigger this flaw in
    privileged container environments.(CVE-2016-4998i1/4%0

"The openSUSE Leap 42.3 kernel was updated to 4.4.159 to receive
various security and bugfixes.

The following security bugs were fixed :

  - CVE-2018-13096: A denial of service (out-of-bounds
    memory access and BUG) can occur upon encountering an
    abnormal bitmap size when mounting a crafted f2fs image
    (bnc#1100062).

  - CVE-2018-13097: There is an out-of-bounds read or a
    divide-by-zero error for an incorrect user_block_count
    in a corrupted f2fs image, leading to a denial of
    service (BUG) (bnc#1100061).

  - CVE-2018-13098: A denial of service (slab out-of-bounds
    read and BUG) can occur for a modified f2fs filesystem
    image in which FI_EXTRA_ATTR is set in an inode
    (bnc#1100060).

  - CVE-2018-13099: A denial of service (out-of-bounds
    memory access and BUG) can occur for a modified f2fs
    filesystem image in which an inline inode contains an
    invalid reserved blkaddr (bnc#1100059).

  - CVE-2018-13100: An issue was discovered in
    fs/f2fs/super.c which did not properly validate
    secs_per_zone in a corrupted f2fs image, as demonstrated
    by a divide-by-zero error (bnc#1100056).

  - CVE-2018-14613: There is an invalid pointer dereference
    in io_ctl_map_page() when mounting and operating a
    crafted btrfs image, because of a lack of block group
    item validation in check_leaf_item in
    fs/btrfs/tree-checker.c (bnc#1102896).

  - CVE-2018-14617: There is a NULL pointer dereference and
    panic in hfsplus_lookup() in fs/hfsplus/dir.c 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
    (bnc#1102870).

  - CVE-2018-14633: A security flaw was found in the
    chap_server_compute_md5() function in the ISCSI target
    code in the Linux kernel in a way an authentication
    request from an ISCSI initiator is processed. An
    unauthenticated remote attacker can cause a stack-based
    buffer overflow and smash up to 17 bytes of the stack.
    The attack requires the iSCSI target to be enabled on
    the victim host. Depending on how the target's code was
    built (i.e. depending on a compiler, compile flags and
    hardware architecture) an attack may lead to a system
    crash and thus to a denial-of-service or possibly to a
    non-authorized access to data exported by an iSCSI
    target. Due to the nature of the flaw, privilege
    escalation cannot be fully ruled out, although we
    believe it is highly unlikely. Kernel versions 4.18.x,
    4.14.x and 3.10.x are believed to be vulnerable
    (bnc#1107829).

  - CVE-2018-16276: Local attackers could use user access
    read/writes with incorrect bounds checking in the yurex
    USB driver to crash the kernel or potentially escalate
    privileges (bnc#1106095).

  - CVE-2018-16597: Incorrect access checking in overlayfs
    mounts could be used by local attackers to modify or
    truncate files in the underlying filesystem
    (bnc#1106512).

  - CVE-2018-17182: 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).

  - CVE-2018-7480: The blkcg_init_queue function in
    block/blk-cgroup.c allowed local users to cause a denial
    of service (double free) or possibly have unspecified
    other impact by triggering a creation failure
    (bnc#1082863).

  - CVE-2018-7757: Memory leak in the sas_smp_get_phy_events
    function in drivers/scsi/libsas/sas_expander.c allowed
    local users to cause a denial of service (memory
    consumption) via many read accesses to files in the
    /sys/class/sas_phy directory, as demonstrated by the
    /sys/class/sas_phy/phy-1:0:12/invalid_dword_count file
    (bnc#1084536).
