Microsoft Outlook is prone to a remote denial-of-service vulnerability because the application fails to properly handle malformed email messages.
A remote attacker can exploit this issue to crash affected email clients. This issue will persist as long as the email message resides on the mail server, creating a prolonged denial-of-service condition.
