Description

This security bulletin contains information about 2 vulnerabilities.


1) Improper Authentication (CVE-ID: CVE-2026-14935)

CWE-ID: CWE-287 - Improper Authentication

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to bypass authentication.

The vulnerability exists due to improper authentication in webrtcbin SDP fingerprint validation when processing remote descriptions for active media sections. A remote attacker can strip fingerprint attributes from remote SDP signaling to bypass authentication.

This weakens the WebRTC check that binds the DTLS certificate to the signaled identity.


2) Stack-based buffer overflow (CVE-ID: CVE-2026-59692)

CWE-ID: CWE-121 - Stack-based buffer overflow

CVSSv4: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to stack-based buffer overflow in the DTLS connection implementation when verifying peer certificates during the DTLS handshake. A remote attacker can send a certificate with an oversized Subject DN to execute arbitrary code.

The issue can also cause a process crash or data corruption, and can be triggered by a DTLS-SRTP or WebRTC peer during handshake verification.
