Synopsis
=======
A vulnerability has been found in nginx which may allow 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            < 1.4.7                    >= 1.4.7 

Description
==========
A bug in the SPDY implementation in nginx was found which might cause a
heap memory buffer overflow in a worker process by using a specially
crafted request. The SPDY implementation is not enabled in default
configurations.

Impact

A remote attacker could cause execution of arbitrary code by using a
specially crafted request.

Workaround
=========
Disable the spdy module in NGINX_MODULES_HTTP. 

Resolution

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=www-servers/nginx-1.4.7"
