Synopsis

========

 

Multiple vulnerabilities in Apache might lead to a Denial of Service.

 

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 < 2.2.9 >= 2.2.9

 

Description

===========

 

Multiple vulnerabilities have been discovered in Apache:

 

* Dustin Kirkland reported that the mod_ssl module can leak memory

when the client reports support for a compression algorithm

(CVE-2008-1678).

 

* Ryujiro Shibuya reported that the ap_proxy_http_process_response()

function in the mod_proxy module does not limit the number of

forwarded interim responses (CVE-2008-2364).

 

* sp3x of SecurityReason reported a Cross-Site Request Forgery

vulnerability in the balancer-manager in the mod_proxy_balancer

module (CVE-2007-6420).

 

Impact

======

 

A remote attacker could exploit these vulnerabilities by connecting to

an Apache httpd, by causing an Apache proxy server to connect to a

malicious server, or by enticing a balancer administrator to connect to

a specially-crafted URL, resulting in a Denial of Service of the Apache

daemon.

 

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-2.2.9"
