Overview

Affected versions of this package are vulnerable to Buffer Over-read through the ngx_http_mp4_module. An attacker can cause the termination of an NGINX worker process by sending a specially crafted mp4 file.

Note:

This is only exploitable if the mp4 directive is used in the configuration file.
