Synopsis
========

Multiple vulnerabilities have been discovered in Apache.

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 lt; 2.2.8 gt;= 2.2.8

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

Adrian Pastor and Amir Azam (ProCheckUp) reported that the HTTP Method
specifier header is not properly sanitized when the HTTP return code is
"413 Request Entity too large" (CVE-2007-6203). The mod_proxy_balancer
module does not properly check the balancer name before using it
(CVE-2007-6422). The mod_proxy_ftp does not define a charset in its
answers (CVE-2008-0005). Stefano Di Paola (Minded Security) reported
that filenames are not properly sanitized within the mod_negociation
module (CVE-2008-0455, CVE-2008-0456).

Impact
======

A remote attacker could entice a user to visit a malicious URL or send
specially crafted HTTP requests (i.e using Adobe Flash) to perform
Cross-Site Scripting and HTTP response splitting attacks, or conduct a
Denial of Service attack on the vulnerable web server.

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 "gt;=www-servers/apache-2.2.8"
