nginx vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 14.04 LTS

Summary:

nginx could be made to crash if it received specially crafted network
traffic.

Software Description:
- nginx: small, powerful, scalable web/proxy server

Details:

USN-7014-1 fixed a vulnerability in nginx. This update
provides the corresponding update for Ubuntu 14.04 LTS.

Original advisory details:

   It was discovered that the nginx ngx_http_mp4 module incorrectly handled
   certain malformed mp4 files. In environments where the mp4 directive 
is in
   use, a remote attacker could possibly use this issue to cause nginx to
   crash, resulting in a denial of service.

The problem can be corrected by updating your system to the following
package versions:

    nginx                           1.4.6-1ubuntu3.9+esm5

    nginx-full                      1.4.6-1ubuntu3.9+esm5
