Microsoft took the unprecedented step of releasing 10 additional updates for unsupported Windows platforms such as XP and Server 2003. These updates were identified by Microsoft to pose elevated risk of cyber attacks. This is in addition to the normal June 2017 updates for supported platforms and the already released MS17-010. I’ve reviewed the updates and produced the attached spreadsheet mapping exploit code names to patches. These updates should be considered critical, especially CVE-2017-8543 which has the potential to be used similar to WannaCry.
