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_p2 >= 1.8.5_p2 Description =========== The read_multipart function of the CGI library shipped with Ruby (cgi.rb) does not properly check boundaries in MIME multipart content. This is a different issue than GLSA 200611-12. Impact ====== The vulnerability can be exploited by sending the cgi.rb library a crafted HTTP request with multipart MIME encoding that contains a malformed MIME boundary specifier. Successful exploitation of the vulnerability causes the library to go into an infinite loop. 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_p2" References ========== [ 1 ] CVE-2006-6303 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-6303 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200612-21.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.
