The vulnerability could allow a malicious user to run code from an Excel worksheet without the user's knowledge. Frequently asked questions regarding this vulnerability and the patch can be found at: http://www.microsoft.com/technet/security/bulletin/fq00-051.asp Issue ===== A vulnerability has been discovered in REGISTER.ID, a worksheet function, when referencing a DLL created by a malicious user. When REGISTER.ID is invoked from an Excel worksheet it can reference any DLL on the system and can be harmful if the referenced DLL contains malicious code. By design, there is no warning given to the user when REGISTER.ID calls a DLL, from a worksheet. In order for a malicious user to exploit this vulnerability the referenced (malicious) DLL would have to reside on the affected user's computer or on a machine accessible via a UNC path on the user's network.
