CVE-2022-23219 Open this link in a new tabHow to fix?
Upgrade SLES:15.3 glibc-devel to version 2.31-150300.9.12.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream glibc-devel package and not the glibc-devel package as distributed by SLES.
See How to fix? for SLES:15.3 relevant fixed versions and status.
The deprecated compatibility function clnt_create in the sunrpc module of the GNU C Library (aka glibc) through 2.34 copies its hostname argument on the stack without validating its length, which may result in a buffer overflow, potentially resulting in a denial of service or (if an application is not built with a stack protector enabled) arbitrary code execution.
