  - CVE-2017-18269: An SSE2-optimized memmove implementation for i386 did
  not correctly perform the overlapping memory check if the source memory
  range spaned the middle of the address space, resulting in corrupt data
  being produced by the copy operation. This may have disclosed
  information to context-dependent attackers, resulted in a denial of
  service or code execution (bsc#1094150).

  - CVE-2018-11236: Prevent integer overflow on 32-bit architectures when
  processing very long pathname arguments to the realpath function,
  leading to a stack-based buffer overflow (bsc#1094161).

  - CVE-2018-11237: An AVX-512-optimized implementation of the mempcpy
  function may have written data beyond the target buffer, leading to a
  buffer overflow in __mempcpy_avx512_no_vzeroupper (bsc#1092877,
  bsc#1094154).

  This update was imported from the SUSE:SLE-15:Update update project.

  Patch Instructions:

  To install this openSUSE Security Update use the SUSE recommended
  installation methods
  like YaST online_update or 'zypper patch'.

  Alternatively you can run the command listed for your product:

  - openSUSE Leap 15.0:

  zypper in -t patch openSUSE-2018-788=1");

  script_tag(name:"affected", value:"glibc on openSUSE Leap 15.0.");

  script_tag(name:"solution", value:"Please install the updated package(s).");

  script_tag(name:"solution_type", value:"VendorFix");
