Summary:Microsoft Exchange is vulnerable to a denial of service. By connecting to an SMTP port on the vulnerable Exchange server, a remote attacker could send a specially-crafted extended verb request, which are used to communicate Exchange-specific information among Exchange servers, to cause the server to consume a large amount memory. This could cause the SMTP service to crash or cause the server to stop responding to legitimate requests.
