During a DTLS handshake, the peer certificate Subject Distinguished Name is printed into a fixed-size 2048-byte stack buffer without bounds checking.

If WebRTC/DTLS functionality is not required, remove the DTLS plugin shared object from the GStreamer plugins directory (typically /usr/lib64/gstreamer-1.0/libgstdtls.so).\n2. Restrict network access to WebRTC/DTLS endpoints to trusted peers only via firewall rules.\n3.
