Description:
Multiple vulnerabilities were reported in Microsoft Malware Protection Engine. A remote user can cause arbitrary code to be executed on the target system. A local user can cause denial of service conditions on the target system.
A remote user can create a specially crafted file that, when scanned by the target Microsoft Malware Protection Engine, will execute arbitrary code on the target system [CVE-2017-8538, CVE-2017-8540, CVE-2017-8541]. The code will run with LocalSystem privileges.
A remote user can create a specially crafted file that, when scanned by the target Microsoft Malware Protection Engine, will cause a scan timeout on the target system [CVE-2017-8535, CVE-2017-8536, CVE-2017-8537, CVE-2017-8539, CVE-2017-8542]. As a result, the Microsoft Malware Protection Engine service will not monitor the target system until the service is restarted.
Mateusz Jurczyk of Google Project Zero reported these vulnerabilities.

Impact:
A remote user can create content that, when loaded by the target user, will execute arbitrary code with LocalSystem privileges on the target system.
A local user can prevent the target Microsoft Malware Protection Engine from monitoring the target system. A service restart is required to return the system to normal operations.
