"According to its version number, the instance of MediaWiki running
on the remote host is affected by the following remote code execution
vulnerabilities :

  - A user-input validation error exists during thumbnail
    generation in the 'thumb.php' script that allows the
    execution of arbitrary shell commands via a specially
    crafted DjVu file.

  - A user-input validation error exists in the
    'pdfhandler_body.php' script used by the PdfHandler
    extension that allows the execution of arbitrary shell
    commands via a specially crafted PDF file.

Note that Nessus has not tested for these issues but has instead
relied only on the application's self-reported version number. Also
note that the affected features are not enabled by default.");
