CVE-2018-16845

nginx before versions 1.15.6, 1.14.1 has a vulnerability in the
ngx_http_mp4_module, which might allow an attacker to cause infinite loop
in a worker process, cause a worker process crash, or might result in
worker process memory disclosure by using a specially crafted mp4 file. The
issue only affects nginx if it is built with the ngx_http_mp4_module (the
module is not built by default) and the .mp4. directive is used in the
configuration file. Further, the attack is only possible if an attacker is
able to trigger processing of a specially crafted mp4 file with the
ngx_http_mp4_module.
