Microsoft Exchange IMAP Command Processing Remote Denial of Service Vulnerability

Microsoft Exchange IMAP Command Processing Remote Denial of Service Vulnerability

Microsoft Exchange is prone to a remote denial-of-service vulnerability because it fails to properly handle specially crafted IMAP commands.

Successfully exploiting this issue allows remote attackers to cause targeted Exchange servers' mail service to stop responding, thus denying further email service for legitimate users. To recover from the denial-of-service condition, administrators must restart the IIS Admin Service service.
