An exploitable denial of service vulnerability exists in the GstRTSPAuth functionality of GStreamer/gst-rtsp-server 1.14.5. A specially crafted RTSP setup request can cause a null pointer deference resulting in denial-of-service. An attacker can send a malicious packet to trigger this vulnerability.
The product does not check for an error after calling a function that can return with a NULL pointer if the function fails, which leads to a resultant NULL pointer dereference.
