|MS09-003||Vulnerabilities in Microsoft Exchange Could Allow Remote Code Execution (959239)||Microsoft Exchange||Critical||11-02-2009|
Brief overview of the risk:
A remote code execution vulnerability exists in the way Microsoft Exchange Server decodes the Transport Neutral Encapsulation Format (TNEF) data for a message.
Detailed Information on the risk:
This security update resolves two privately reported vulnerabilities in Microsoft Exchange Server. 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.
