About Libreswan
Libreswan patches four CVEs on two lines, two of them credited to Claude and Ada Logics.
Libreswan is an IPsec VPN implementation for Linux and the BSDs. On October 5 it released 5.4.1 and 5.3.3 together: 5.4.1 fixes three CVEs (null-pointer crashes on unexpected EAP and empty PKCS7 payloads, and a use-after-free on EOF in IKE over TCP), and 5.3.3 fixes the same three plus a FIPS certificate-leak denial of service. v5.4 in August remains the latest feature release, adding ML-KEM 768 post-quantum key exchange via RFC 9370.
