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. An attacker can exploit this by providing a crafted file to the utility, leading to an application crash (Denial of Service). While primarily a DoS risk, use-after-free vulnerabilities can sometimes be leveraged for arbitrary code execution depending on the memory layout and allocator behavior.
