Technical details
A denial of service vulnerability exists in the SMB (Server Message Block) implementation of Windows NT 4.0. The flaw is triggered when the system processes a malformed SMB logon request where the actual payload size differs from the size specified in the packet header. A remote, unauthenticated attacker can exploit this by sending a crafted packet to the target system, leading to a system crash or hang. Microsoft addressed this issue in Knowledge Base article 180963.
