This update resolves the "Unchecked buffer in the Multiple UNC Provider" security vulnerability in Windows NTŪ 4.0, 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.

For more information about this vulnerability, read Microsoft Security Bulletin MS02-017.
