NVD Description

Note: Versions mentioned in the description apply only to the upstream glibc-i18ndata package and not the glibc-i18ndata package as distributed by SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

An SSE2-optimized memmove implementation for i386 in sysdeps/i386/i686/multiarch/memcpy-sse2-unaligned.S in the GNU C Library (aka glibc or libc6) 2.21 through 2.27 does not correctly perform the overlapping memory check if the source memory range spans the middle of the address space, resulting in corrupt data being produced by the copy operation. This may disclose information to context-dependent attackers, or result in a denial of service, or, possibly, code execution.
