Description Alexandros Toptsoglou 2019-01-21 15:03:55 UTC 
The string component in the GNU C Library (aka glibc or libc6) through 2.28,
when running on the x32 architecture, incorrectly attempts to use a 64-bit
register for size_t in assembly codes, which can lead to a segmentation fault or
possibly unspecified other impact, as demonstrated by a crash in
__memmove_avx_unaligned_erms in
sysdeps/x86_64/multiarch/memmove-vec-unaligned-erms.S during a memcpy.

Comment 1 Alexandros Toptsoglou 2019-01-21 15:05:12 UTC 
SUSE does not ship x32 architecture.
