CyberRota Analysis
AI-GeneratedA NULL pointer dereference vulnerability in GStreamer's RTSP support library allows remote, unauthenticated attackers to crash the server by sending a specially crafted malformed request with manipulated whitespace in the Authorization or WWW-Authenticate header. This flaw can also be exploited against RTSP clients by compromised servers, resulting in a denial of service without affecting data confidentiality or integrity. Organizations using GStreamer for RTSP services should prioritize patching this vulnerability to prevent potential service disruptions.

Original NVD Description
A NULL pointer dereference flaw was found in GStreamer's RTSP support library. The vulnerability occurs while parsing an Authorization or WWW-Authenticate header that uses Digest authentication. Specially crafted whitespace placement around a parameter's terminator can cause an internal length calculation to underflow, leading to a crash of the process parsing the header. On an RTSP server this can be triggered by a remote, unauthenticated attacker sending a single malformed request when the server has authentication enabled; the same flaw can also be triggered against an RTSP client by a malicious or compromised RTSP server. Successful exploitation results in a denial of service (application crash) and has no confirmed impact on confidentiality or integrity.
