DNS: Microsoft Exchange Crafted MX Record
This signature detects attempts to exploit a known vulnerability in the way that Microsoft Windows Simple Mail Transfer Protocol (SMTP) component handles specially crafted DNS Mail Exchanger (MX) resource records. Because authentication is not required, an attacker can exploit this flaw by sending a specially crafted network message to a computer running the SMTP service. A successful attack can result in a denial-of-service condition.
Extended Description
The Microsoft Windows Simple Mail Transfer Protocol (SMTP) Server is prone to a denial-of-service vulnerability.
Successful exploits will cause the affected SMTP server to stop responding, denying service to legitimate users.
