| विवरण | A vulnerability was found in GPAC up to commit f1219cde (2026-07-25) and classified as problematic. Affected is the function gf_node_list_add_child in the file scenegraph/base_scenegraph.c (line 1521) of the component MP4Box. The manipulation via a crafted MP4 file processed with the -nstatx argument leads to a segmentation fault due to invalid pointer dereference. It is possible to launch the attack locally. User interaction is required.
Technical Details
- Affected file/function: scenegraph/base_scenegraph.c:1521 / gf_node_list_add_child
- Vulnerable parameter: ADD-child scene command targeting invalid parent node in embedded scene graph
- Attack vector: Local
- Privileges required: None
- Trigger condition: Processing a crafted MP4 file with "MP4Box -nstatx" causes gf_sg_command_apply to pass an invalid parent node pointer to gf_node_insert_child then gf_node_list_add_child
Impact
- Confidentiality: None
- Integrity: None
- Availability: High
