Executive brief
GPAC MP4Box, a widely used tool for processing and editing multimedia files, contains a security flaw in how it handles memory. An attacker can exploit this by providing a specially crafted MP4 file to the application. If processed, the application will likely crash, leading to a denial of service that could disrupt media processing workflows or automated video conversion pipelines.
Technical details
A heap use-after-free vulnerability exists in GPAC MP4Box v2.4 within the gf_node_get_tag function located in scenegraph/base_scenegraph.c. The flaw is triggered when the application attempts to access memory that has already been freed during the processing of a malformed MP4 file. This is a local attack vector requiring the victim to open or process a malicious file. Successful exploitation typically results in an application crash (Denial of Service), though use-after-free vulnerabilities can sometimes be leveraged for arbitrary code execution depending on the memory layout and allocator state.
