CVE-2020-6095Public exploitNetwork attack vector

Unauthenticated server crash via NULL authorization lookup

Published Mar 27, 2020 · Updated Aug 4, 2024

NULL pointer dereference in GstRTSPAuth in GStreamer RTSP Server 1.14.5 allows remote attackers to crash an RTSP server. In default_authenticate, an oversized Basic Authorization header yields a NULL authorization value that is passed to g_hash_table_lookup and then g_str_hash. Reachability requires an RTSP server configured with GstRTSPAuth to accept the crafted SETUP request; no data disclosure or modification is reported.
