About Libreswan
IPsec daemon shipping back-to-back CVE releases, one of them found by an AI audit.
Libreswan is an IKE/IPsec implementation, and its recent visible releases are entirely security-driven: 5.3.1 addressed three CVEs, and 5.3.2 followed a month later with a single one. The 5.3.2 note discloses that the project ran an AI-assisted audit of its own codebase, which surfaced an assertion failure reachable through a malformed X.509 certificate in FIPS mode. The older entries in this feed are raw commit-log dumps from the 4.x and 5.0rc era rather than curated notes.
