  "description": "Libreswan is an implementation of IKEv1 and IKEv2 for IPsec. IPsec is the Internet Protocol Security and uses strong cryptography to provide both authentication and encryption services.  These services allow you to build secure tunnels through untrusted networks.  Everything passing through the untrusted net is encrypted by the ipsec gateway machine and decrypted by the gateway at the other end of the tunnel.  The resulting tunnel is a virtual private network or VPN.\r\n\r\nSecurity Fix(es):\r\n\r\nThe Libreswan Project was notified of an issue causing libreswan to restart when using IKEv1 without specifying an esp= line. When the peer requests AES-GMAC, libreswan's default proposal handler causes an assertion failure and crashes and restarts. IKEv2 connections are not affected.(CVE-2024-3652)",
