Some versions of Microsoft Windows 2000 feature an SMTP service for handling Internet email. A flaw in this SMTP service may result in a denial-of-service vulnerability.
When a message with a corrupted time stamp is received by a vulnerable system, the SMTP service may stop responding or shut down unexpectedly. This issue may occur when the FILETIME attribute of the message is not valid.
According to Microsoft, this issue affects systems running Microsoft Windows 2000 Server with Service Pack 2 or Service Pack 3 installed and systems running Microsoft Exchange 2000 Server.
The SMTP service may stop responding or shut down unexpectedly, resulting in a denial of service.
Microsoft has included a patch for this issue in Windows 2000 Service Pack 4. For additional information, users are encouraged to review the following Microsoft Knowledge Base Articles:
