NVD Description

Note: Versions mentioned in the description apply only to the upstream pacemaker-cli package and not the pacemaker-cli package as distributed by Centos. See How to fix? for Centos:10 relevant fixed versions and status.

A flaw was found in Pacemaker. An unauthenticated remote attacker can exploit an integer overflow vulnerability in the remote message decompression process. By sending a specially crafted compressed remote message before authentication, an attacker can cause memory corruption, leading to a denial of service (DoS) in the CIB remote listener. This can result in the affected service crashing.
