Title: Microsoft Windows UDP Socket DoS Vulnerability
Severity: MODERATE
Description:
Microsoft Windows 2000 and Windows 98 are subject to a denial of service condition. Receiving a maliciously crafted email or visiting a malicious web site could prevent Windows 2000 from DNS resolution and Windows 98 from accepting new TCP connections.
This bug may also cause the consumption of system resources. Windows fails to reserve available UDP sockets for local applications. Receiving a maliciously crafted email or visiting a malicious web site could allow the utilization of available UDP sockets, consuming all system resources.
Closing the malicious application or a restart of the machine is required in order to gain normal functionality.
It should be noted that upon closing the application in question, it has been known that the machine may unexpectedly reboot.
Successful exploitation of this vulnerability could assist in further attacks against the victim host.
