CVE-2024-50665Public exploit

Process crash via null auxiliary-information pointer

Published Jan 23, 2025 · Updated Jan 28, 2025

Null pointer dereference in GPAC MP4Box 2.4 allows local users to crash the process by opening a crafted encrypted MP4 file. isom_cenc_get_sai_by_saiz_saio reads an auxiliary-information byte through a null pointer while processing CENC sample metadata. A user must cause MP4Box to process attacker-supplied media during DASH segmentation; the demonstrated result is process termination without data disclosure or modification.
