A use-after-free vulnerability has been identified in GPAC version 26.08-DEV, specifically within the MP4Box component. The issue arises in the 'gf_node_deactivate_ex' function, located in 'src/scenegraph/base_scenegraph.c'. This vulnerability can be exploited locally, leading to a null pointer dereference and a segmentation fault. The problem occurs when the scene graph deactivation process is applied to an untrusted scene graph, causing a stack overflow due to unbounded recursion. After several recursive calls, the function attempts to access a node pointer that has been invalidated, resulting in a crash.
Users are advised to upgrade to GPAC version abi-16.24, which addresses this vulnerability.
