Background ========== Trac is a minimalistic web-based project management, wiki and bug tracking system including a Subversion interface. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-apps/trac < 0.8.4 >= 0.8.4 Description =========== Stefan Esser of the Hardened-PHP project discovered that Trac fails to validate the "id" parameter when uploading attachments to the wiki or the bug tracking system. Impact ====== A remote attacker could exploit the vulnerability to upload arbitrary files to a directory where the webserver has write access to, possibly leading to the execution of arbitrary code. Workaround ========== There is no known workaround at this time. Resolution ========== All Trac users should upgrade to the latest available version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-apps/trac-0.8.4" References ========== [ 1 ] Hardened PHP Advisory 012005 http://www.hardened-php.net/advisory-012005.php Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200506-21.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.
