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.

The remote host is affected by the vulnerability described in GLSA-201206-07 (nginx: User-assisted execution of arbitrary code)

    An error in ngx_http_mp4_module.c could cause a buffer overflow.
    NOTE: nginx must have been emerged with USE='nginx_modules_http_mp4' in       order to be affected by this vulnerability.
  Impact :

    A remote attacker could entice a user to place a specially crafted MP4       file on the nginx server, possibly resulting in execution of arbitrary       code with the privileges of the process or a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

Update to 1.0.15

Update to 1.0.15 and enable _hardened_build

The remote host is running a nginx HTTP server. 

 Versions earlier than 1.0.15(stable version) or versions earlier than 1.1.19(development version) are vulnerable to a buffer-overflow vulnerability because it fails to perform adequate checks on user-supplied input. An attacker can exploit this issue by using a specially-crafted mp4 file, allowing the attacker to execute arbitrary code in the context of the application. (CVE-2012-2089)

The nginx project reports :

Buffer overflow in the ngx_http_mp4_module

The remote web server is running nginx, a lightweight, high performance web server / reverse proxy and email (IMAP/POP3) proxy. 

According to its Server response header, the installed version of nginx is between 1.0.7 and 1.0.14 or 1.1.3 and 1.1.18 and is, therefore, affected by a buffer overflow vulnerability. 

An error in the module 'ngx_http_mp4_module' can allow a specially crafted mp4 file to cause a buffer overflow and can potentially allow arbitrary code execution. 

Note that successful exploitation requires that the 'mp4' configuration option is enabled and the module 'ngx_http_mp4_module' is enabled. Nessus has not checked for either of these settings.
