Name of the Vulnerable Software and Affected Versions
Pacemaker (affected versions not specified)
Description
An integer overflow exists in the remote message decompression process. An unauthenticated remote attacker can exploit this by sending a specially crafted compressed remote message before authentication, causing memory corruption. This leads to a denial of service (DoS) in the CIB remote listener, resulting in the affected service crashing.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
