[GLSA]

Gentoo Linux Security Advisory

Title: Apache: Denial of Service (GLSA 200807-06)
Severity: normal
Exploitable: remote
Date: July 09, 2008
Bug(s): #222643, #227111
ID: 200807-06

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: www-servers/apache
Vulnerable: < 2.2.9
Unaffected: >= 2.2.9
Architectures: All supported architectures


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:
