CVE-2026-50810 Details
Description
A NULL pointer dereference in smooth_parse_stream_index() in src/media_tools/mpd.c in GPAC master HEAD before commit b35c61f104b85fbb16520ac2838d5d2ef70845b5 allows attackers to cause a denial of service
A NULL pointer dereference vulnerability has been identified in GPAC versions prior to the latest commit b35c61f104b85fbb16520ac2838d5d2ef70845b5. This vulnerability occurs in the Smooth Streaming manifest conversion process within the file 'src/media_tools/mpd.c', specifically in the function 'smooth_parse_stream_index()'. Attackers can exploit this vulnerability to cause a denial-of-service condition by crafting a Smooth Streaming manifest file that lacks a 'Url' attribute, leading to a crash when the parser attempts to process the data.
Users can update to the latest version of GPAC, which includes the necessary null checks in the 'smooth_parse_stream_index()' function to prevent the dereference.
