Description:
First Last has reported a weakness in Window Washer, which can be exploited by malicious people to disclose "securely" deleted data on a disk.

The problem is that the "Add Bleach to Wash" security setting, which should delete a file securely by overwriting it multiple times with random data, doesn't do this properly.

Successful exploitation allows a malicious person to recover the deleted data using various unspecified publicly available tools.

The weakness has been reported in version 5.5. Other versions may also be affected.

Solution:
The weakness has reportedly been fixed in version 5.5.1.240.

Provided and/or discovered by:
First Last, wbglinks.net.

Changelog:
2005-01-03: Updated "Solution" section.
