Executive Summary

This vulnerability is a heap buffer overflow found in the function gf_isom_vp_config_new within the isomedia/avc_ext.c file of GPAC MP4Box version 2.4.

An attacker can exploit this flaw by supplying a specially crafted MP4 file, which causes the program to overwrite memory improperly on the heap.

This improper memory handling can lead to a Denial of Service (DoS) condition, crashing or disrupting the normal operation of the software.

Impact Analysis

The primary impact of this vulnerability is that an attacker can cause a Denial of Service (DoS) by crashing the GPAC MP4Box application.

This means that if you use GPAC MP4Box to process MP4 files, an attacker could disrupt your service or workflow by providing a maliciously crafted MP4 file.
