This update resolves the "Unchecked buffer in the Multiple UNC Provider" security vulnerability in Windows 2000, and is discussed in Microsoft Security Bulletin MS02-017. Download now to prevent a malicious user from exploiting a buffer overflow vulnerability to either cause your computer to restart or to run unauthorized programs on your computer.
The vulnerability results because of a flaw in the Multiple UNC (uniform naming convention) Provider (MUP), which is a network file system resource locator that runs in kernel-mode memory in Windows. Due to an unchecked buffer (a temporary storage area of limited capacity), a malicious user can send a specially malformed request, and either cause the computer to restart or run programs as if he or she were the user.
