Background ========== MoinMoin is a Python clone of WikiWiki, based on PikiPiki. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-www/moinmoin <= 1.2.1 >= 1.2.2 Description =========== MoinMoin contains a bug in the code handling administrative group ACLs. A user created with the same name as an administrative group gains the privileges of the administrative group. Impact ====== If an administrative group called AdminGroup existed an attacker could create a user called AdminGroup and gain the privileges of the group AdminGroup. This could lead to unauthorized users gaining administrative access. Workaround ========== For every administrative group with special privileges create a user with the same name as the group. Resolution ========== All users should upgrade to the latest available version of MoinMoin, as follows: # emerge sync # emerge -pv ">=net-ww/moinmoin-1.2.2" # emerge ">=net-ww/moinmoin-1.2.2" References ========== [ 1 ] MoinMoin Announcement http://sourceforge.net/tracker/index.php?func=detail&aid=948103&group_id=8482&atid=108482 [ 2 ] OSVDB Entry http://www.osvdb.org/6704 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200407-09.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.
