4DescriptionCVE.org
A vulnerability was determined in GPAC 26.07.0. Affected by this issue is the function gf_node_del of the file scenegraph/base_scenegraph.c of the component MP4Box. This manipulation causes out-of-bounds read. The attack is restricted to local execution. The exploit has been publicly disclosed and may be utilized. Upgrading to version abi-16.23 can resolve this issue. Patch name: afca1f1181668d85941d51ed1adf647807d5d975. It is advisable to upgrade the affected component.
AnalysisAI
Out-of-bounds read in GPAC 26.07.0's MP4Box tool occurs when a NULL node pointer is passed to gf_node_del() in scenegraph/base_scenegraph.c, causing a process crash when parsing a crafted media or scene-graph file. The fix commit (afca1f1181668d85941d51ed1adf647807d5d975) addresses multiple related input-validation deficiencies across the scene graph, LASeR decoder, MPEG video reframer, and BT scene loader. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires local execution: the attacker must be able to supply a crafted media or scene file to a user or script that processes it with MP4Box from GPAC 26.07.0. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 0.9 accurately reflects constrained impact: local attack vector, low-privileged execution, passive user interaction (the user or an automated job must invoke MP4Box against a crafted file), and a worst-case outcome of VA:L - a process crash with no confidentiality or integrity effect. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade GPAC to release abi-16.23 or any later release that incorporates patch commit afca1f1181668d85941d51ed1adf647807d5d975 (https://github.com/gpac/gpac/commit/afca1f1181668d85941d51ed1adf647807d5d975). … Detailed patch versions, workarounds, and compensating controls in full report. |
