Background ========== The Horde Application Framework is a general-purpose web application framework written in PHP, providing classes for handling preferences, compression, browser detection, connection tracking, MIME and more. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-apps/horde < 3.1.7 >= 3.1.7 2 www-apps/horde-groupware < 1.0.5 >= 1.0.5 3 www-apps/horde-kronolith < 2.1.7 >= 2.1.7 4 www-apps/horde-mnemo < 2.1.2 >= 2.1.2 5 www-apps/horde-nag < 2.1.4 >= 2.1.4 6 www-apps/horde-webmail < 1.0.6 >= 1.0.6 ------------------------------------------------------------------- 6 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== Multiple vulnerabilities have been reported in the Horde Application Framework: * David Collins, Patrick Pelanne and the HostGator.com LLC support team discovered that the theme preference page does not sanitize POST variables for several options, allowing the insertion of NULL bytes and ".." sequences (CVE-2008-1284). * An error exists in the Horde API allowing users to bypass security restrictions. Impact ====== The first vulnerability can be exploited by a remote attacker to read arbitrary files and by remote authenticated attackers to execute arbitrary files. The second vulnerability can be exploited by authenticated remote attackers to perform restricted operations. Workaround ========== There is no known workaround at this time. Resolution ========== All Horde Application Framework users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-apps/horde-3.1.7" All horde-groupware users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-apps/horde-groupware-1.0.5" All horde-kronolith users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-apps/horde-kronolith-2.1.7" All horde-mnemo users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-apps/horde-mnemo-2.1.2" All horde-nag users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-apps/horde-nag-2.1.4" All horde-webmail users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-apps/horde-webmail-1.0.6" References ========== [ 1 ] CVE-2008-1284 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1284 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200805-01.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.
