CVE-2023-0841Public exploitNetwork attack vector

Application crash via skipped-byte bounds error

Published Feb 15, 2023 · Updated Feb 13, 2025

Heap-buffer overflow in GPAC 2.3-DEV-rev40-g3602a5ded allows remote attackers to crash MP4Box via a crafted MP3 file. mp3_dmx_process checks the frame size against remaining input without adding bytes already skipped, then copies beyond the heap buffer. Exploitation requires a user to process the file; the demonstrated consequence is an application abort.
