Background ========== DokuWiki is a simple to use wiki targeted at developer teams, workgroups and small companies. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-apps/dokuwiki < 20060309-r1 >= 20060309-r1 Description =========== Stefan Esser discovered that the DokuWiki spell checker fails to properly sanitize PHP's "complex curly syntax". Impact ====== A unauthenticated remote attacker may execute arbitrary PHP commands - and thus possibly arbitrary system commands - with the permissions of the user running the webserver that serves DokuWiki pages. 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-20060309-r1" References ========== [ 1 ] Hardened-PHP advisory http://www.hardened-php.net/advisory_042006.119.html [ 2 ] CVE-2006-2878 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2878 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200606-16.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.
