Synopsis
========

Multiple vulnerabilities have been found in nginx, the worst of 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           < 1.4.1-r2               >= 1.4.1-r2

Description
===========

Multiple vulnerabilities have been discovered in nginx. Please review
the CVE identifiers referenced below for details.

Impact
======

A remote attacker could send a specially crafted request, possibly
resulting in execution of arbitrary code with the privileges of the
process, or a Denial of Service condition. Furthermore, a
context-dependent attacker may be able to obtain sensitive information.

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-1.4.1-r2"
