CVE-2023-0770Public exploit

Process crash via recursive BIFS scene route

Published Feb 9, 2023 · Updated Aug 2, 2024

Stack overflow in GPAC before 2.2 allows local users to crash MP4Box by processing a crafted MPEG-4 BIFS scene file. The gf_sg_proto_field_is_sftime_offset function recursively follows a ProtoNode route back to the same node without terminating the cycle, exhausting the process stack. User interaction is required to process the crafted file; public evidence demonstrates a process crash but not code execution.
