CVE-2025-60497 · Severity: info · Published 2026-10-21

MP4Box is a multimedia tool used to inspect and process MP4 video files. A null pointer dereference vulnerability in its MP4 parsing code allows an attacker to crash the application by supplying a specially crafted MP4 file, resulting in a denial of service.

Technologies: [GPAC Project MP4Box](https://junglewise.ai/threats/technologies/gpac-project-mp4box). Vendors: [GPAC Project](https://junglewise.ai/threats/vendors/gpac-project).

## How to fix

- Fixed in 2.5

## Technical details

A null pointer dereference occurs in the GetESD function (isomedia/track.c) when processing a corrupted MP4 sample description (stsd) entry. The code attempts to dereference a null pointer without checking if the pointer is non-null before accessing its members. The fix adds a bounds check (dpnd && dpnd->trackIDCount) to prevent dereferencing a null pointer when processing stream dependencies.

## Affected products

- GPAC Project MP4Box before 2.5
