Technical details
A stack-based buffer overflow exists in the gf_sg_dom_event_bubble function within src/scenegraph/dom_events.c of the MP4Box component in GPAC. The vulnerability is triggered through manipulation of DOM event processing, allowing memory corruption on the stack. The attack vector is local; an attacker must provide a malicious media file that will be processed locally. This could lead to denial of service through a crash or potentially arbitrary code execution. The vulnerability has been patched in version abi-16.23 (commit 9eb40df4448b88d6a6ce3454657c06f47eff0b24).
