moin vulnerability

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

  • Ubuntu 9.04
  • Ubuntu 8.10

Software description

  • moin


It was discovered that MoinMoin did not properly sanitize its input when
attaching files, resulting in cross-site scripting (XSS) vulnerabilities.
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.

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

Ubuntu 9.04:
python-moinmoin 1.8.2-2ubuntu2.1

In general, a standard system upgrade is sufficient to effect the
necessary changes.
