Background ========== WordPress is a popular personal publishing platform with a web interface. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-apps/wordpress < 2.0.6 >= 2.0.6 Description =========== When decoding trackbacks with alternate character sets, WordPress does not correctly sanitize the entries before further modifying a SQL query. WordPress also displays different error messages in wp-login.php based upon whether or not a user exists. David Kierznowski has discovered that WordPress fails to properly sanitize recent file information in /wp-admin/templates.php before sending that information to a browser. Impact ====== An attacker could inject arbitrary SQL into WordPress database queries. An attacker could also determine if a WordPress user existed by trying to login as that user, better facilitating brute force attacks. Lastly, an attacker authenticated to view the administrative section of a WordPress instance could try to edit a file with a malicious filename; this may cause arbitrary HTML or JavaScript to be executed in users' browsers viewing /wp-admin/templates.php. Workaround ========== There is no known workaround at this time. Resolution ========== All WordPress users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-apps/wordpress-2.0.6" References ========== [ 1 ] CVE-2006-6808 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-6808 [ 2 ] CVE-2007-0107 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0107 [ 3 ] CVE-2007-0109 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0109 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200701-10.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.
