Description

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.
