CVE-2023-29573Public exploit

Process crash via unbounded track-run entry allocation

Published Apr 13, 2023 · Updated Feb 7, 2025

Resource exhaustion in Bento4 mp4info 1.6.0-639 allows local users to crash the process by opening a crafted MP4 file. The AP4_TrunAtom constructor passes the parsed track-run entry count to AP4_Array::SetItemCount, which expands the array until EnsureCapacity requests about 32 GiB. A user must cause mp4info to process the malformed file; the demonstrated consequence is process termination from memory exhaustion, not code execution.
