Description Jan Lieskovsky 2012-03-28 10:38:36 EDT
Starting from PolicyKit version v0.103 the following upstream change:

http://cgit.freedesktop.org/PolicyKit/commit/?id=763faf434b445c20ae9529100d3ef5290976d0c9

of the default value of AdminIdentities variable of the PolicyKit Local Authority configuration enabled the local users, belonging to the 'wheel' group to be allowed to authenticate, when administrator authentication was needed. A local user, member of the 'wheel' group could use this default policy configuration settings to become privileged user (root) without providing a password. While this change has been applied by the PolicyKit upstream intentionally, some distributions are considering this change to impersonate a security flaw.
