DESCRIPTION:
Igor Franchuk has discovered a weakness in Microsoft Windows, which
can be exploited to hide certain information.

The weakness is caused due to an error in the Registry Editor Utility
(regedt32.exe) when handling long string names. This can be exploited
to hide strings in a registry key by creating a string with a long
name, which causes this string and any subsequently created strings
in the key to be hidden.

Successful exploitation e.g. makes it possible for malware to hide
strings in the "Run" registry key. However, these hidden strings
created after the string with the overly long name will still be
executed when the user logs in.

The weakness has been confirmed in a fully updated Windows XP SP2
system, and has also been reported in Windows 2000. Other versions
may also be affected.

SOLUTION:
Ensure that systems have up-to-date anti-virus and spyware detection
software installed.
