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.
