How to fix?

Upgrade SLES:15.0 glibc-i18ndata to version 2.26-13.3.1 or higher.

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.

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.
