About FreeSWITCH
With the legacy purge done, FreeSWITCH spent 1.11.2 bounds-checking everything that parses bytes
FreeSWITCH shipped 1.11.2 in August 2026, three months after the 1.11.0 branch cut that removed roughly thirty modules and migrated the regex engine to PCRE2. Where 1.11.0 was about deleting surface area, 1.11.2 is about auditing what remains: nearly every bug line is a bounds or length check in a parser — STUN attributes, base64 decode, XML entity decoding, RTMP H.264 NAL units, XML-RPC WebSocket frames, MSRP body lengths. Alongside the fixes it adds an interface allowlist and turns on DTLS client-certificate verification against the SDP fingerprint plus opt-in STUN MESSAGE-INTEGRITY checks on inbound ICE. The build system continues moving off self-hosted infrastructure onto GitHub-published artifacts and upstream packages.
