"According to its Sever response header, the installed version of nginx is 1.0.x prior to 1.0.15 or 1.1.x prior to
1.1.19. It is, therefore, affected by the following issue :

  - Buffer overflow in ngx_http_mp4_module.c in the ngx_http_mp4_module module in nginx 1.0.7 through 1.0.14
    and 1.1.3 through 1.1.18, when the mp4 directive is used, allows remote attackers to cause a denial of
    service (memory overwrite) or possibly execute arbitrary code via a crafted MP4 file. (CVE-2012-2089)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
