Background ========== The Apache HTTP server is one of the most popular web servers on the internet. mod_ssl provides SSL v2/v3 and TLS v1 support for Apache 1.3 and is also included in Apache 2. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-www/apache < 2.0.52 >= 2.0.52 < 2.0 2 net-www/mod_ssl < 2.8.20 >= 2.8.20 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== A flaw has been found in mod_ssl where the "SSLCipherSuite" directive could be bypassed in certain configurations if it is used in a directory or location context to restrict the set of allowed cipher suites. Impact ====== A remote attacker could gain access to a location using any cipher suite allowed by the server/virtual host configuration, disregarding the restrictions by "SSLCipherSuite" for that location. Workaround ========== There is no known workaround at this time. Resolution ========== All Apache 2 users should upgrade to the latest version: # emerge sync # emerge -pv ">=net-www/apache-2.0.52" # emerge ">=net-www/apache-2.0.52" All mod_ssl users should upgrade to the latest version: # emerge sync # emerge -pv ">=net-www/mod_ssl-2.8.20" # emerge ">=net-www/mod_ssl-2.8.20" References ========== [ 1 ] CAN-2004-0885 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0885 [ 2 ] Apache HTTPD Bug 31505 http://issues.apache.org/bugzilla/show_bug.cgi?id=31505 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200410-21.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.
