Lifecycle Timeline
2DescriptionCVE.org
A flaw has been found in GPAC up to f1219cde. Affected by this vulnerability is the function gf_node_get_field_count of the file scenegraph/base_scenegraph.c of the component MP4Box. Executing a manipulation can lead to reachable assertion. It is possible to launch the attack on the local host. The exploit has been published and may be used. Upgrading to version abi-16.23 addresses this issue. This patch is called 49dee5cad329cfed310c1682703df7daa47df31a. You should upgrade the affected component.
AnalysisAI
Reachable assertion failures in GPAC's MP4Box tool through commit f1219cde allow a local attacker to crash the process by supplying a crafted MP4 or MPEG-4 BIFS scene graph file. The flaw originates in gf_node_get_field_count (scenegraph/base_scenegraph.c), where hard gf_assert() calls - and a structural field-ordering mismatch in nodes_mpeg4.h between adjacent MPEG-4 node type definitions - allow malformed input to reach an assert that aborts the process. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires local access to a system where GPAC MP4Box is installed (AV:L). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 0.9 accurately captures the negligible real-world severity: the attack is strictly local (AV:L), requires low OS privileges (PR:L) and user interaction (UI:P), and the only observable impact is a process-level crash (VA:L) with zero confidentiality or integrity consequence. … 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 the abi-16.23 release, which incorporates the fix committed as 49dee5cad329cfed310c1682703df7daa47df31a (https://github.com/gpac/gpac/commit/49dee5cad329cfed310c1682703df7daa47df31a). … Detailed patch versions, workarounds, and compensating controls in full report. |
