   An update that solves three vulnerabilities and has two
   fixes is now available.

Description:

   This update for glibc fixes the following security issues:

   - 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 writen data beyond the target buffer, leading to a
     buffer overflow in __mempcpy_avx512_no_vzeroupper (bsc#1092877,
     bsc#1094154).
