Security Update, August 29, 2001

This update resolves a privilege elevation vulnerability in Windows 2000, and is discussed in Microsoft Security Bulletin MS01-047. Download now to prevent a malicious user from gaining unauthorized privileges on your domain.

This vulnerability exists because there is an error in the way that a Windows 2000 domain accepts authorization data from a trusted domain. This causes the affected domain to accept any Security Identifier (SID) that is specified within the authorization data of the trusted domain, even if the SID is not from the trusted domain. The vulnerability could allow a malicious user to gain unauthorized privileges on the domain.
