# GPAC MP4Box: crafted MP4 file crashes the tool via stack overflow

MP4Box from GPAC before 2.5 has a stack overflow in its BIFS decoding function (gf_bifs_dec_node in /bifs/field_decode.c). A crafted MP4 file can crash the process, causing a denial of service.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Run `MP4Box -version` and compare against `2.5`
- unknown

## Fix

- Upgrade GPAC to `2.5` or later
- unknown

## From the sources

A stack overflow in the gf_bifs_dec_node function (/bifs/field_decode.c) of GPAC Project/MP4Box before 2.5 allows attackers to cause a Denial of Service (DoS) via supplying a crafted MP4 file.
