Details
A security vulnerability has been detected in GPAC up to 2.4.0. Affected by this issue is the function Media_GetSample of the file src/isomedia/media.c of the component MP4Box. Such manipulation of the argument cat leads to memory leak. The attack can only be performed from a local environment. The exploit has been disclosed publicly and may be used. The name of the patch is e79c5cbe8b3fed27f4854ec229457d30c96206f1. It is best practice to apply a patch to resolve this issue.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
