DESCRIPTION:
Two vulnerabilities have been reported in the Fill PDF module for
Drupal, which can be exploited by malicious users to compromise a
vulnerable system and by malicious people to bypass certain security
restrictions.

1) An error due to a missing argument in the "fillpdf_merge_pdf()"
function in fillpdf.module can be exploited to bypass the
authorization mechanism via a specially crafted web request.

This vulnerability is reported in versions prior to 7.x-1.2.

2) Input passed via imported templates is not properly sanitised in
the "fillpdf_form_export_decode()" function in fillpdf.admin.inc
before being used in an "eval()" call. This can be exploited to
execute arbitrary PHP code.

Successful exploitation of this vulnerability requires the
"administer PDFs" permission.

This vulnerability is reported in versions prior to 6.x-1.16 and
versions prior to 7.x-1.2.

SOLUTION:
Update to a fixed version.
