Description

The 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).
