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" References ========== [ 1 ] CVE-2007-6420 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-6420 [ 2 ] CVE-2008-1678 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1678 [ 3 ] CVE-2008-2364 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-2364 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200807-06.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.
