| Description | A vulnerability was found in GPAC up to commit f1219cde (2026-07-25) and classified as problematic. Affected is the function gf_sm_dump_command_list in the file scene_manager/scene_dump.c:2911 of the component MP4Box. The manipulation via a crafted MP4 file processed with the -bt argument leads to a reachable assertion failure (assert(!sdump->current_com_list)) caused by residual non-NULL state in the scene dump structure. It is possible to launch the attack locally. User interaction is required.Technical Details- Affected file/function: scene_manager/scene_dump.c:2911 / gf_sm_dump_command_list with assertion assert(!sdump->current_com_list)- Vulnerable parameter: Crafted MP4 with malformed ISO data and corrupted scene dump state- Attack vector: Local- Privileges required: None- Trigger condition: Processing a crafted MP4 file with "MP4Box -bt" causes the scene dump state machine to reach a state where current_com_list is unexpectedly non-NULL. Requires --enable-debug build.Impact- Confidentiality: None- Integrity: None- Availability: HighCVSS v3.1Score: 5.5 (Medium)Vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:HTimeline- Discovered: 2026-07-27- Vendor notified: 2026-07-27- Patch released: 2026-07-28- Public disclosure: 2026-07-27CountermeasureApply the upstream patch. Replace the reachable assertion with proper error handling that resets or gracefully handles the corrupted scene dump state. |
