Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

CVE-2024-2357:
A flaw was found in Libreswan. This issue causes 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 automatically added on startup using the auto= keyword, it can cause repeated crashes, leading to a denial of service.
