Background ========== Ruby is a dynamic, open source programming language with a focus on simplicity and productivity. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-lang/ruby < 1.8.5-r3 >= 1.8.5-r3 Description =========== Zed Shaw, Jeremy Kemper, and Jamis Buck of the Mongrel project reported that the CGI library shipped with Ruby is vulnerable to a remote Denial of Service by an unauthenticated user. Impact ====== The vulnerability can be exploited by sending the cgi.rb library an HTTP request with multipart MIME encoding that contains a malformed MIME boundary specifier beginning with "-" instead of "--". Successful exploitation of the vulnerability causes the library to go into an infinite loop waiting for additional non-existent input. Workaround ========== There is no known workaround at this time. Resolution ========== All Ruby users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-lang/ruby-1.8.5-r3" References ========== [ 1 ] CVE-2006-5467 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-5467 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200611-12.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.
