Background ========= MoinMoin is a Python clone of WikiWiki, based on PikiPiki. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-www/moinmoin = 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 ;aid=948103&group_id=8482&atid=108482 [ 2 ] OSVDB Entry Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200407-09 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.
