Threats Tagged 'cve-2026-14935'

Multiple security vulnerabilities have been identified and fixed in the gstreamer-plugins-bad component. These include out-of-bounds reads and writes, heap and stack buffer overflows, and improper validation issues affecting various parsers such as H.264, H.265, H.266, WebRTC, IPv4/TCP headers, and DTLS handshake processing. The issues could lead to memory corruption or crashes. No CVSS score is provided, but the severity is assessed as high due to the nature of the vulnerabilities.

A logic vulnerability was found in GStreamer's webrtcbin component. The _check_sdp_crypto() function contains an inverted boolean condition that causes it to accept remote SDP offers or answers that lack the required a=fingerprint attribute, while incorrectly rejecting those that include it. 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.
