Hello, welcome to this month's blog on the Microsoft patch release. This month the vendor is releasing five bulletins covering a total of 23 vulnerabilities. Nineteen of this month's issues are rated ’Critical’.

As always, customers are advised to follow these security best practices:

  • Install vendor patches as soon as they are available.
  • Run all software with the least privileges required while still maintaining functionality.
  • Avoid handling files from unknown or questionable sources.
  • Never visit sites of unknown or questionable integrity.
  • Block external access at the network perimeter to all key systems unless specific access is required.
