A heap use-after-free vulnerability has been identified in GPAC versions prior to the commit fixing this issue. The vulnerability occurs in the MP4Box component, specifically within the 'gf_sg_script_load' function of 'scenegraph/vrml_tools.c'. The issue arises when the scenegraph parser processes malformed XMT files, leading to the application of a scene command that references a previously freed script node. This vulnerability can be exploited remotely, causing memory corruption that could extend beyond a denial-of-service condition, depending on the state of the memory allocator and the context in which GPAC is embedded.
Users are advised to upgrade to GPAC version abi-16.23 or later, where this vulnerability has been fixed.
