How to fix?

Upgrade Centos:8 python3-rpm to version 0:4.14.3-14.el8_4 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python3-rpm package and not the python3-rpm package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

A flaw was found in RPM's signature check functionality when reading a package file. This flaw allows an attacker who can convince a victim to install a seemingly verifiable package, whose signature header was modified, to cause RPM database corruption and execute code. The highest threat from this vulnerability is to data integrity, confidentiality, and system availability.
