Patch status is confirmed by the vendor advisory.
Description
A stack buffer overflow vulnerability exists in GStreamer's DTLS plugin where the peer certificate Subject Distinguished Name is copied into a fixed-size 2048-byte stack buffer without bounds checking. This can be triggered by a remote unauthenticated attacker sending a certificate with an oversized Subject DN, causing a stack buffer overflow and process crash, resulting in denial of service.
