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).
