CVE-2023-29575Public exploit

Process crash via unbounded MP4 entry allocation

Published Apr 21, 2023 · Updated Feb 4, 2025

Resource exhaustion in Bento4 mp42aac 1.6.0-639 allows local users to crash the process by opening a crafted MP4 file. AP4_TrunAtom passes an attacker-controlled trun entry count to AP4_Array::SetItemCount, causing an approximately 32 GiB allocation without an effective bound. Exploitation requires a user to run mp42aac against the file; the demonstrated consequence is process termination, with no reported data disclosure or modification.
