  • SLES for SAP Applications 11-SP4
  • SUSE Linux Enterprise Server 11 SP4
  • SUSE Linux Enterprise Software Development Kit 11 SP4

An update that solves three vulnerabilities and has four security fixes can now be installed.

Description:

The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

  • CVE-2018-1087: And an unprivileged KVM guest user could use this flaw to potentially escalate their privileges inside a guest. (bsc#1087088)
  • CVE-2018-8897: An unprivileged system user could use incorrect set up interrupt stacks to crash the Linux kernel resulting in DoS issue. (bsc#1087088)
  • CVE-2018-10124: 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 (bnc#1089752).

The following non-security bugs were fixed:

  • kvm/x86: fix icebp instruction handling (bsc#1087088).
  • media: cpia2: Fix a couple off by one bugs (bsc#1050431).
  • nfs: add nostatflush mount option (bsc#1065726).
  • nfs: allow flush-on-stat to be disabled (bsc#1065726).
  • powerpc/fadump: Add a warning when 'fadump_reserve_mem=' is used (bnc#1032084, FATE#323225).
  • powerpc/fadump: reuse crashkernel parameter for fadump memory reservation (bnc#1032084, FATE#323225).
  • powerpc/fadump: update documentation about crashkernel parameter reuse (bnc#1032084, FATE#323225).
  • powerpc/fadump: use 'fadump_reserve_mem=' when specified (bnc#1032084, FATE#323225).
  • x86/entry/64: Do not use IST entry for #BP stack (bsc#1087088).
