Overview

Affected versions of this package are vulnerable to Out-of-bounds Read in the ngx_http_mp4_module process. An attacker can cause termination of the worker process or potentially execute arbitrary code by supplying a specially crafted MP4 file. This is only exploitable if the module is built with ngx_http_mp4_module and the mp4 directive is enabled in the configuration, and the attacker can trigger processing of a malicious MP4 file.
