Background ========== DokuWiki is a wiki targeted at developer teams, workgroups and small companies. It does not use a database backend. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-apps/dokuwiki < 20060309e >= 20060309e Description =========== Input validation flaws have been discovered in the image handling of fetch.php if ImageMagick is used, which is not the default method. Impact ====== A remote attacker could exploit the flaws to execute arbitrary shell commands with the rights of the web server daemon or cause a Denial of Service. Workaround ========== There is no known workaround at this time. Resolution ========== All DokuWiki users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-apps/dokuwiki-20060309e" References ========== [ 1 ] DokuWiki Announcement http://www.freelists.org/archives/dokuwiki/09-2006/msg00278.html Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200609-20.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.
