## How to fix

- Fixed in GPAC 2.5

## Technical details

A NULL pointer dereference exists in the gf_isom_get_esd function (isomedia/isom_read.c:1386) where code fails to validate pointer states before accessing media descriptor structures. An attacker can trigger this via a crafted XML file supplied to MP4Box with the -dnal option, causing a segmentation fault. The vulnerability has been patched.

## Affected products

- GPAC Project MP4Box before 2.5
