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 (CVE-2017-18269).

stdlib/canonicalize.c in the GNU C Library (aka glibc or libc6) 2.27 and
earlier, when processing very long pathname arguments to the realpath function,
could encounter an integer overflow on 32-bit architectures, leading to a
stack-based buffer overflow and, potentially, arbitrary code execution
(CVE-2018-11236).");
