An attacker with the ability to intercept and modify WebRTC signaling messages could exploit this to bypass the SDP-level DTLS certificate fingerprint binding, weakening defenses against man-in-the-middle attacks on media streams.(CVE-2026-14935)\n\nA stack buffer overflow vulnerability was found in GStreamer\u0026apos;s DTLS plugin. During a DTLS handshake, the peer certificate Subject Distinguished Name is printed into a fixed-size 2048-byte stack buffer without bounds checking. A remote unauthenticated attacker can send a certificate with an oversized Subject DN that exceeds the buffer, causing a stack buffer overflow and process crash, resulting in denial of service.(CVE-2026-59692)","status":"published","published":"2026-08-30T04:18:32Z","modified":"2026-08-30T04:32:43.343260452Z","cvss":[{"version":"3.1","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","level":"high"}],"updated_at":"2026-11-02T15:52:47.217107Z"},{"id":"UBUNTU-CVE-2026-14935","description":"A logic vulnerability was found in GStreamer's webrtcbin component.
