Technical details
The Windows Internet Name Service (WINS) in Windows NT 3.51 and 4.0 is vulnerable to a remote denial of service attack. An attacker can send a flood of malformed packets to the WINS service (typically on port 42). This causes the service to consume excessive CPU and memory resources while simultaneously flooding the system event logs with error messages. The resulting resource exhaustion can lead to severe performance degradation or a complete system hang. The attack is unauthenticated and can be launched over the network using raw sockets to transmit garbage data to the target service.
Affected products
- Microsoft Windows NT 3.51, 4.0
