NVD Description

Note: Versions mentioned in the description apply only to the upstream rpm-libs package and not the rpm-libs package as distributed by RHEL. See How to fix? for RHEL: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.
