Fedora 38 upgrades libreswan to resolve CVE-2024-2357, implementing improved measures for encryption and overall security.
Update to 4.14 for CVE-2024-2357, v6 SAN name and TFC padding fix for AEAD

Summary

Libreswan is a free implementation of IPsec & IKE for Linux. 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.

This package contains the daemons and userland tools for setting up

Libreswan.

Libreswan also supports IKEv2 (RFC7296) and Secure Labeling

Libreswan is based on Openswan-2.6.38 which in turn is based on FreeS/WAN-2.04
