  "title": "Device Guard Code Integrity Policy Security Feature Bypass Vulnerability",
  "description": "\u003Cp\u003EA security feature bypass vulnerability exists in Device Guard that could allow an attacker to inject malicious code into a Windows PowerShell session. An attacker who successfully exploited this vulnerability could inject code into a trusted PowerShell process to bypass the Device Guard Code Integrity policy on the local machine.\u003C/p\u003E\n\u003Cp\u003ETo exploit the vulnerability, an attacker would first have to access the local machine, and then inject malicious code into a script that is trusted by the Code Integrity policy. The injected code would then run with the same trust level as the script and bypass the Code Integrity policy.\u003C/p\u003E\n\u003Cp\u003EThe update addresses the vulnerability by correcting how PowerShell exposes functions and processes user supplied code.\u003C/p\u003E",
