How to fix?

Upgrade Centos:8 glibc-minimal-langpack to version 0:2.28-164.el8_5.3 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream glibc-minimal-langpack package and not the glibc-minimal-langpack package as distributed by Centos. See How to fix? for Centos:8 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.
