- 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,
