The vulnerability could allow denial of service if the Microsoft Malware Protection Engine scans a specially crafted file.

The Microsoft Malware Protection Engine ships with several Microsoft antimalware products. See the Affected Software section for a list of affected products. Updates to the Microsoft Malware Protection Engine are installed along with the updated malware definitions for the affected products. Administrators of enterprise installations should follow their established internal processes to ensure that the definition and engine updates are approved in their update management software, and that clients consume the updates accordingly. Typically, no action is required of enterprise administrators or end users to install updates for the Microsoft Malware Protection Engine, because the built-in mechanism for the automatic detection and deployment of updates will apply the update within 48 hours of release. The exact time frame depends on the software used, Internet connection, and infrastructure configuration. *Affected Software* The following software is affected by the vulnerability *Antimalware Software* *Severity* *Impact* Microsoft Forefront Client Security Important Denial of Service Microsoft Forefront Endpoint Protection 2010 Important Denial of Service Microsoft Forefront Security for SharePoint Service Pack 3 Important Denial of Service Microsoft System Center 2012 Endpoint Protection Important Denial of Service Microsoft System Center 2012 Endpoint Protection Service Pack 1 Important Denial of Service Microsoft Malicious Software Removal Tool – (May 2014 or earlier versions) Important Denial of Service Microsoft Security Essentials Important Denial of Service Microsoft Security Essentials Prerelease Important Denial of Service Windows Defender for Windows 8, Windows 8.1, Windows Server 2012, and Windows Server 2012 R2 Important Denial of Service Windows Defender for Windows RT and Windows RT 8.1 Important Denial of Service Windows Defender for Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2 Important Denial of Service Windows Defender Offline Important Denial of Service Windows Intune Endpoint Protection Important Denial of Service *Last version of the Microsoft Malware Protection Engine affected by this vulnerability*: Version 1.1.10600.0 *First version of the Microsoft Malware Protection Engine with this vulnerability addressed*: Version 1.1.10701.0* *If your version of the Microsoft Malware Protection Engine is equal to or greater than this version, then you are not affected by this vulnerability and do not need to take any further action.
