Ubuntu Security Notice 1604-1 - It was discovered that MoinMoin did not properly sanitize certain input, resulting in a cross-site scripting (XSS) vulnerability. With cross-site scripting vulnerabilities, if a user were tricked into viewing server output during a crafted server request, a remote attacker could exploit this to modify the contents, or steal confidential data, within the same domain. It was discovered that MoinMoin incorrectly handled group names that contain virtual group names such as "All", "Known" or "Trusted". This could result in a remote user having incorrect permissions. Various other issues were also addressed.

Debian Linux Security Advisory 2538-1 - It was discovered that Moin, a Python clone of WikiWiki, incorrectly evaluates ACLs when virtual groups are involved. This may allow certain users to have additional permissions (privilege escalation) or lack expected permissions.
