    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
    MoinMoin could be made to run programs and overwrite files.
    Software Description:
    - moin: Collaborative hypertext environment
    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.
