UBUNTU-CVE-2026-59692 (CVE-2026-59692)

Vulnerability from osv_ubuntu – Published: 2026-07-09 11:16 – Updated: 2026-07-15 17:53 – Source website

Details

A stack buffer overflow vulnerability was found in GStreamer'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.

Severity

7.5 (High)
