Synopsis

Description

The remote Rocky Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RLSA-2024:1998 advisory.

 - The Libreswan Project was notified of an issue causing libreswan to restart under some IKEv2 retransmit scenarios when a connection is configured to use PreSharedKeys (authby=secret) and the connection cannot find a matching configured secret. When such a connection is automatically added on startup using the auto= keyword, it can cause repeated crashes leading to a Denial of Service. (CVE-2024-2357)
