The first vulnerability could allow remote code execution if a specially crafted TNEF message is sent to a Microsoft Exchange Server. An attacker who successfully exploited this vulnerability could take complete control of the affected system with Exchange Server service account privileges. The second vulnerability could allow denial of service if a specially crafted MAPI command is sent to a Microsoft Exchange Server. An attacker who successfully exploited this vulnerability could cause the Microsoft Exchange System Attendant service and other services that use the EMSMDB32 provider to stop responding.
