Microsoft Exchange iCal Request Remote Denial of Service Vulnerability

Microsoft Exchange iCal Request Remote Denial of Service Vulnerability

Microsoft Exchange is prone to a remote denial-of-service vulnerability because it fails to properly handle unexpected iCal message content.

Successfully exploiting this issue allows remote attackers to cause targeted Exchange servers to stop responding to further requests for sending, receiving, or accessing email. As a result, denial-of-service conditions occur for legitimate users of affected servers. A denial-of-service condition will persist until an administrator restarts the Microsoft Exchange Information Store service.
