7.44 or 8.x prior to 8.1.3. It is, therefore, affected by the
following vulnerabilities :

  - A flaw exists in the Views module that allows an
    unauthenticated, remote attacker to bypass restrictions
    and disclose the number of hits collected by the
    Statistics module.

  - A flaw exists in the User module due to incorrectly
    granting the 'all user' role when saving user accounts.
    An authenticated, remote attacker can exploit this to
    gain elevated privileges.

Note that Nessus has not tested for these issues but has instead
relied only on the application's self-reported version number.");

If some specific contributed or custom code triggers a rebuild of the

the site. This would typically result in the user gaining
administrative access.

For Debian 7 'Wheezy', this issue has been fixed in drupal7 version
7.14-2+deb7u14.

We recommend that you upgrade your drupal7 packages.
