Background ========== Ruby on Rails is a free web framework used to develop database-driven web applications. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-ruby/rails < 1.2.5 >= 1.2.5 Description =========== candlerb found that ActiveResource, when processing responses using the Hash.from_xml() function, does not properly sanitize filenames (CVE-2007-5380). The session management functionality allowed the "session_id" to be set in the URL (CVE-2007-5380). BCC discovered that the to_json() function does not properly sanitize input before returning it to the user (CVE-2007-3227). Impact ====== Unauthenticated remote attackers could exploit these vulnerabilities to determine the existence of files or to read the contents of arbitrary XML files; conduct session fixation attacks and gain unauthorized access; and to execute arbitrary HTML and script code in a user's browser session in context of an affected site by enticing a user to browse a specially crafted URL. Workaround ========== There is no known workaround at this time. Resolution ========== All Ruby on Rails users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-ruby/rails-1.2.5" References ========== [ 1 ] CVE-2007-3227 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3227 [ 2 ] CVE-2007-5379 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5379 [ 3 ] CVE-2007-5380 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5380 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200711-17.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.
