Title:	nginx: User-assisted execution of arbitrary code
Date:	06/21/2012
Bugs:	#411751
ID:	201206-07

Synopsis

A buffer overflow vulnerability in nginx could result in the execution of arbitrary code.

Background

nginx is a robust, small, and high performance HTTP and reverse proxy server.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
www-servers/nginx	< 1.0.15	>= 1.0.15	All supported architectures

Description

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.

Resolution

All nginx users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=www-servers/nginx-1.0.15"
