Background ========== The Apache HTTP server is one of the most popular web servers on the Internet. mod_imap provides support for server-side image maps; mod_ssl provides secure HTTP connections. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-www/apache < 2.0.55-r1 >= 2.0.55-r1 *>= 2.0.54-r16 == 1.3.34-r2 *>= 1.3.34-r11 Description =========== Apache's mod_imap fails to properly sanitize the "Referer" directive of imagemaps in some cases, leaving the HTTP Referer header unescaped. A flaw in mod_ssl can lead to a NULL pointer dereference if the site uses a custom "Error 400" document. These vulnerabilities were reported by Marc Cox and Hartmut Keil, respectively. Impact ====== A remote attacker could exploit mod_imap to inject arbitrary HTML or JavaScript into a user's browser to gather sensitive information. Attackers could also cause a Denial of Service on hosts using the SSL module (Apache 2.0.x only). Workaround ========== There is no known workaround at this time. Resolution ========== All Apache users should upgrade to the latest version, depending on whether they still use the old configuration style (/etc/apache/conf/*.conf) or the new one (/etc/apache2/httpd.conf). 2.0.x users, new style config: # emerge --sync # emerge --ask --oneshot --verbose ">=net-www/apache-2.0.55-r1" 2.0.x users, old style config: # emerge --sync # emerge --ask --oneshot --verbose "=net-www/apache-2.0.54-r16" 1.x users, new style config: # emerge --sync # emerge --ask --oneshot --verbose "=net-www/apache-1.3.34-r11" 1.x users, old style config: # emerge --sync # emerge --ask --oneshot --verbose "=net-www/apache-1.3.34-r2" References ========== [ 1 ] CVE-2005-3352 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3352 [ 2 ] CVE-2005-3357 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3357 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200602-03.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
