Description

Microsoft Windows is prone to a remote code-execution vulnerability. Successful exploits allow attackers to execute arbitrary code in the context of the host operating system. Failed exploit attempts will result in a denial of service condition.

Technologies Affected

  • Microsoft Hyper-V
  • Microsoft Windows 10 Version 1607 for x64-based Systems
  • Microsoft Windows 10 Version 1709 for ARM64-based Systems
  • Microsoft Windows 10 Version 1803 for ARM64-based Systems
  • Microsoft Windows 10 Version 1803 for x64-based Systems
  • Microsoft Windows 10 Version 1809 for ARM64-based Systems
  • Microsoft Windows 10 Version 1809 for x64-based Systems
  • Microsoft Windows 10 Version 1903 for ARM64-based Systems
  • Microsoft Windows 10 Version 1903 for x64-based Systems
  • Microsoft Windows 10 for x64-based Systems
  • Microsoft Windows 10 version 1703 for x64-based Systems
  • Microsoft Windows 10 version 1709 for x64-based Systems
  • Microsoft Windows 8.1 for x64-based Systems
  • Microsoft Windows RT 8.1
  • Microsoft Windows Server 1803
  • Microsoft Windows Server 1903
  • Microsoft Windows Server 2012
  • Microsoft Windows Server 2012 R2
  • Microsoft Windows Server 2016
  • Microsoft Windows Server 2019

Recommendations

Run all software as a nonprivileged user with minimal access rights.
To reduce the impact of latent vulnerabilities, always run nonadministrative software as an unprivileged user with minimal access rights.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to monitor network traffic for signs of suspicious or anomalous activity. This may help detect malicious actions that an attacker may take after successfully exploiting vulnerabilities in applications. Review all applicable logs regularly.

Do not accept or execute files from untrusted or unknown sources.
To reduce the likelihood of successful exploits, never handle files that originate from unfamiliar or untrusted sources.

Do not follow links provided by unknown or untrusted sources.
Web users should be cautious about following links to sites that are provided by unfamiliar or suspicious sources. Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.

Implement multiple redundant layers of security.
Since this issue may be leveraged to execute code, we recommend memory-protection schemes, such as nonexecutable stack/heap configurations and randomly mapped memory segments. This tactic may complicate exploits of memory-corruption vulnerabilities.

Updates are available. Please see the references or vendor advisory for more information.
