moin vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in MoinMoin.

Software Description:
- moin: Collaborative hypertext environment

Details:

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. (CVE-2011-1058)

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. (CVE-2012-4404)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.04 LTS:
  python-moinmoin                 1.9.3-1ubuntu2.1

Ubuntu 11.10:
  python-moinmoin                 1.9.3-1ubuntu1.11.10.1

Ubuntu 11.04:
  python-moinmoin                 1.9.3-1ubuntu1.11.04.1

Ubuntu 10.04 LTS:
  python-moinmoin                 1.9.2-2ubuntu3.2

In general, a standard system update will make all the necessary changes.
