|---|
| Описание | A vulnerability was found in GPAC up to commit f1219cde (2026-07-25) and classified as problematic. Affected is a function in the scene graph node management of the component MP4Box. The manipulation via a crafted MP4 file processed with the -info argument leads to a reachable assertion failure (assert(node)) that causes an immediate process abort. It is possible to launch the attack locally. User interaction is required.
Technical Details
- Affected file/function: scenegraph/base_scenegraph.c:2002 / gf_node_get_field_count
- Vulnerable parameter: Malformed XMT scene graph with mismatched node types and unknown ProtoInstance fields leading to NULL node reference
- Attack vector: Local
- Privileges required: None
- Trigger condition: Processing a crafted MP4 file with "MP4Box -info" triggers XMT scene parsing that encounters malformed node type declarations and an unknown ProtoInstance field. This leads to a NULL node pointer being passed to gf_node_get_field_count at base_scenegraph.c:2002, triggering assert(node). Requires --enable-debug build.
Impact
- Confidentiality: None
- Integrity: None
- Availability: High
CVSS v3.1
Score: 5.5 (Medium)
