Security Update, April 17, 2000






Read Me First

This update eliminates the "Malformed TCP/IP Print Request" vulnerability found in the TCP/IP Printing Services for Windows NT 4.0 and Windows 2000 (in Windows 2000, the service is referred to as "Print Services for Unix"). This is an optional service used primarily in mixed Windows NT-Unix environments, and is not installed by default. Installing this update will prevent a malicious user from disrupting printing services on a network that has installed TCP/IP Printing Services. The native Windows NT and Windows 2000 printing service is not affected by this vulnerability.
