Background ========== eGroupWare is a suite of web-based group applications including calendar, address book, messenger and email. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-apps/egroupware < 1.4.004 >= 1.4.004 Description =========== A vulnerability has been reported in FCKEditor due to the way that file uploads are handled in the file editor/filemanager/upload/php/upload.php when a filename has multiple file extensions (CVE-2008-2041). Another vulnerability exists in the _bad_protocol_once() function in the file phpgwapi/inc/class.kses.inc.php, which allows remote attackers to bypass HTML filtering (CVE-2008-1502). Impact ====== The first vulnerability can be exploited to upload malicious files and execute arbitrary PHP code provided that a directory is writable by the webserver. The second vulnerability can be exploited by remote attackers via a specially crafted URL in order to conduct cross-site scripting attacks. Workaround ========== There is no known workaround at this time. Resolution ========== All eGroupWare users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-apps/egroupware-1.4.004" References ========== [ 1 ] CVE-2008-1502 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1502 [ 2 ] CVE-2008-2041 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-2041 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200805-04.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.
