CVE-2026-42225

PJSIP is a free and open source multimedia communication library written in C. Prior to version 2.17, on GnuTLS builds, the SIP TLS transport (sip_transport_tls) can accept connections with invalid or untrusted certificates even when the application explicitly enables certificate verification via verify_server = PJ_TRUE or verify_client = PJ_TRUE. This issue has been patched in version 2.17.

Summary		(es) PJSIP es una biblioteca de comunicación multimedia de código abierto y gratuita escrita en C. Antes de la versión 2.17, en las compilaciones de GnuTLS, el transporte SIP TLS (sip_transport_tls) puede aceptar conexiones con certificados no válidos o no confiables incluso cuando la aplicación habilita explícitamente la verificación de certificados a través de verify_server = PJ_TRUE o verify_client = PJ_TRUE. Este problema ha sido parcheado en la versión 2.17.
