Last Modified:
Description
A vulnerability was found in NGINX’s module, ngx_http_mp4_module. This flaw allows a local attacker to cause a worker process crash or might result in worker process memory disclosure by using a specially crafted audio or video file. The issue affects only NGINX products built with ngx_http_mp4_module when the mp4 directive is used in the configuration file. Further, the attack is possible only if an attacker can trigger the processing of a specially crafted audio or video file with ngx_http_mp4_module.
Mitigation
A mitigation for this vulnerability would be to disable the ngx_http_mp4_module module in your local Nginx environment.
