CVE-2023-0866Public exploit

Crash via unchecked ADTS frame size

Published Feb 16, 2023 · Updated Mar 18, 2025

Heap-based buffer overflow in GPAC before 2.3.0-DEV allows local users to crash MP4Box by opening a crafted ADTS media file. In adts_dmx_process, an input-derived ADTS frame size drives memcpy without verifying that the calculated source span remains within buffered data. Processing requires user interaction; the demonstrated result is an out-of-bounds read and abort, while the upstream report also identifies possible code execution.
