| Description | GPAC before 26.02.0 contains a type confusion vulnerability in ctxload_process() that passes non-object descriptors to ODS_SetupOD() without checking the descriptor tag. Attackers can supply a crafted XMT file with a URL-bearing descriptor that crashes MP4Box or other GPAC-based applications in gf_scene_ns_connect_object(), causing denial of service. |
