CVE-2023-29584Public exploitNetwork attack vector

Application crash via unchecked profile buffer read

Published Apr 14, 2023 · Updated Feb 6, 2025

Heap buffer overflow in MP4v2 before 2.1.3 allows attackers to crash applications by supplying a crafted MP4 file. MP4GetVideoProfileLevel obtains a one-byte elementary-stream configuration buffer, then reads four bytes from it without validating the returned size. Processing the attacker-controlled file is required; the published proof demonstrates an out-of-bounds read and process abort, not code execution.
