With the recent CVE bulletin, Microsoft Security Advisory CVE-2018-0875: Hash Collision can cause Denial of Service, it warrants us to update PowerShell Core to 6.0.2 and .NET Core to 2.0.6.

This post covers updating PowerShell Core and .NET Core packages using Homebrew, the Microsoft-recommend method for installing/managing these packages. This method can be used any time you want to update either package:

  1. Open Terminal.
  2. Run brew update (It will appear nothing is happening but watch the window title bar)
  3. Run brew cask upgrade powershell
  4. Run brew cask upgrade dotnet
  5. Once completed, run pwsh to load PowerShell. You should see 6.0.2 (or the newest version) at the top:
