| Описание | A SEGV (segmentation fault) vulnerability exists in GPAC master (commit f1219cde, 2026-07-25). The issue occurs in the gf_node_list_insert_child function in scenegraph/base_scenegraph.c at line 1441 via MP4Box -nstatx. The stats path applies an INSERT scene command from an untrusted embedded scene graph without validating the target node, causing a dereference of an invalid pointer. The call chain is: gf_node_insert_child -> gf_sg_command_apply -> dump_isom_scene_stats. The vulnerability can be triggered with: MP4Box -nstatx poc. PoC and ASan crash log are available in the GitHub issue report. |
