DESCRIPTION:
Some vulnerabilities have been reported in the IMCE Module for
Drupal, which can be exploited by malicious users to delete files or
compromise a vulnerable system.

1) The file deletion functionality does not correctly verify relative
paths before deleting files. Depending on the permissions of the web
server, this can be exploited by malicious users with the "delete
files" permissions to delete arbitrary files.

2) An error exists within the handling of file uploads where a
filename has multiple extensions. This can e.g. be exploited to
execute arbitrary PHP code if a users has the "file upload"
permission.

The vulnerabilities have been reported in versions 4.7 where the CVS
$Id$ field in the imce.module file is older than "$Id: imce.module,v
1.6 2006/09/29 13:50:57 ufku Exp $".

SOLUTION:
Update to the latest version.
