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.
