Description
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the ngx_http_mp4_module when reading mp4 files. A remote attacker can pass a specially crafted file to the web server, trigger an out-of-bounds read error and perform a denial of service (DoS) attack.
Successful exploitation of the vulnerability requires that the server is built with the ngx_http_mp4_module and the "mp4" directive is used in the configuration file.

Install updates from vendor's website.
