Detailed Description The hotfix (916803) for 'Remote Code Execution Vulnerability in Microsoft Exchange' has not been applied. Microsoft Exchange Server 2000 with the Exchange 2000 Post-Service Pack 3 Update Rollup of August 2004 (870540) and Microsoft Exchange Server 2003 SP1 and SP2 could allow a remote attacker to execute arbitrary code on the system when an Exchange Server processes an email with certain vCal or iCal properties. An attacker could exploit the vulnerability by constructing a specially crafted message containing malformed iCal or vCal properties that could potentially allow remote code execution when a user opens or previews a malicious e-mail message. An attacker who successfully exploited this vulnerability could take complete control of an affected system.

* Note: This check requires an account with Guest or upper privileges which can access the registry of the remote host to scan. Absence of these condition will result in the check not being performed and a False Negative for all vulnerable hosts.
