==========================================================================
Ubuntu Security Notice USN-1680-1
December 30, 2012

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

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

- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 10.04 LTS

Summary:

MoinMoin could be made to run programs and overwrite files.

Software Description:
- moin: Collaborative hypertext environment

Details:

It was discovered that MoinMoin did not properly sanitize its input when
processing AnyWikiDraw and TWikiDraw actions. A remote attacker with write
access could exploit this to overwrite arbitrary files and execute
arbitrary code with the priviliges of the web server (user 'www-data').

It was discovered that MoinMoin also did not properly sanitize its input
when processing the AttachFile action. A remote attacker could exploit
this to overwrite files via directory traversal.

Update instructions:

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

Ubuntu 12.10:
  python-moinmoin                 1.9.3-1ubuntu3.1

Ubuntu 12.04 LTS:
  python-moinmoin                 1.9.3-1ubuntu2.2

Ubuntu 11.10:
  python-moinmoin                 1.9.3-1ubuntu1.11.10.2

Ubuntu 10.04 LTS:
  python-moinmoin                 1.9.2-2ubuntu3.3

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