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

-------------------------------------------------------------------

1 www-servers/nginx < 1.0.15 >= 1.0.15

 

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"
