Synopsis
========

Multiple vulnerabilities have been discovered in Apache, possibly
resulting in a Denial of Service or the disclosure of sensitive
information.

Background
==========

The Apache HTTP server is one of the most popular web servers on the
Internet.

Affected packages
=================

    -------------------------------------------------------------------
     Package             /  Vulnerable  /                   Unaffected
    -------------------------------------------------------------------
  1  www-servers/apache       < 2.2.6                    *>= 2.0.59-r5
                                                              >= 2.2.6

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

Multiple cross-site scripting vulnerabilities have been discovered in
mod_status and mod_autoindex (CVE-2006-5752, CVE-2007-4465). An error
has been discovered in the recall_headers() function in mod_mem_cache
(CVE-2007-1862). The mod_cache module does not properly sanitize
requests before processing them (CVE-2007-1863). The Prefork module
does not properly check PID values before sending signals
(CVE-2007-3304). The mod_proxy module does not correctly check headers
before processing them (CVE-2007-3847).

Impact
======

A remote attacker could exploit one of these vulnerabilities to inject
arbitrary script or HTML content, obtain sensitive information or cause
a Denial of Service.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Apache users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-servers/apache-2.0.59-r5"
