Summary
GPAC, a multimedia framework, is affected by a type confusion flaw in its BIFS scene-graph command handling that can crash the MP4Box tool when it opens a crafted XMT file. The bug is reached locally without logging in, but it requires a user to open the malicious file, and the impact is a denial of service rather than code execution or data theft.

Read the original description
GPAC through 26.07.0 contains a type confusion vulnerability in gf_sg_command_apply() in src/scenegraph/commands.c that fails to verify BIFS field-replace command types match target node fields. Attackers can supply a crafted XMT file opened with MP4Box, such as via chapter import, causing gf_sg_vrml_field_clone() to memcpy from invalid pointers and crash.
