Pacemaker: pacemaker: denial of service via integer overflow in remote message decompression PUBLISHED

Description (CNA)

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.
