Executive Summary

This vulnerability is a NULL pointer dereference in the function gf_isom_get_user_data_count within the isomedia/isom_read.c file of GPAC MP4Box version 2.4. It occurs when the software processes a specially crafted MP4 file, which causes the program to attempt to access memory through a NULL pointer.

This leads to a crash or abnormal termination of the program, resulting in a Denial of Service (DoS) condition.

Impact Analysis

The primary impact of this vulnerability is that an attacker can cause a Denial of Service (DoS) by supplying a maliciously crafted MP4 file to the vulnerable GPAC MP4Box software.

This means the software may crash or become unavailable, potentially disrupting services or workflows that depend on it.
