DESCRIPTION:
A vulnerability has been reported in the FileField Sources module for
Drupal, which can be exploited by malicious users to compromise a
vulnerable system.

The vulnerability is caused due to the module not properly sanitising
file extensions when transferring files from a remote server. This can
be exploited to transfer scripts to the server and potentially execute
arbitrary PHP code.

Successful exploitation requires create or edit permissions on a node
that has a "FileField" with "FileField Sources" configured for it.

The vulnerability is reported in versions prior to 6.x-1.2.

SOLUTION:
Update to version 6.x-1.2.
