Description

The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.162 to receive
various security and bugfixes.

The following security bugs were fixed:

• CVE-2018-14633: A security flaw was found in the
  chap_server_compute_md5() function in the ISCSI target code in a way an
  authentication request from an ISCSI initiator is processed. An
  unauthenticated remote attacker can cause a stack 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. (bnc#1107829).
• CVE-2018-18281: The mremap() syscall performs TLB flushes after dropping
  pagetable locks. If a syscall such as ftruncate() removes entries from
  the pagetables of a task that is in the middle of mremap(), a stale TLB
  entry can remain for a short time that permits access to a physical page
  after it has been released back to the page allocator and reused.
  (bnc#1113769).
• CVE-2018-18386: drivers/tty/n_tty.c allowed local attackers (who are
  able to access pseudo terminals) to hang/block further usage of any
  pseudo terminal devices due to an EXTPROC versus ICANON confusion in
  TIOCINQ (bnc#1094825).
• CVE-2018-18690: 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
  mishandled ATTR_REPLACE operations with conversion of an attr from short
  to long form (bnc#1105025).
• CVE-2018-18710: An issue was discovered in the Linux kernel 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 (bnc#1113751).
• CVE-2018-9516: A lack of certain checks in the hid_debug_events_read()
  function in the drivers/hid/hid-debug.c file might have resulted in
  receiving userspace buffer overflow and an out-of-bounds write or to the
  infinite loop. (bnc#1108498).
