Other Information
In addition to the Microsoft vulnerabilities included in the December Security Guidance, an advisory was also released today.Microsoft Guidance for cleaning up orphaned keys generated on vulnerable TPMs and used for Windows Hello for Business [ADV190026]
Microsoft has announced that when Windows Hello for Business (WHfb) is used that public keys can persist within Active Directory even after a device is removed. These orphaned public keys could be obtained by an authenticated attacker and, if they were created on TPMs that were affected by CVE-2017-15361, could be used to compute the private key. This could allow for user impersonation. The advisory includes details on the issue along with a PowerShell script for cleaning up orphaned keys as well as keys affected by CVE-2017-15361.
