Most important this month is MS14-021 and MS14-029. MS14-021 was released out of band on May 1st and MS14-029 is new. Both address Internet Explorer vunlerabilities. Also “Important” means “Important” 3 of the 6 Important updates are already being exploited. Everyone’s goal should be to keep all machines fully patched!
Due to the increasing list of problems this update has caused, Microsoft has entended the installation deadline to June 10 (Windows 8.1 Update Requirement Extended: http://blogs.windows.com/windows/b/windowsexperience/archive/2014/05/12/windows-8-1-update-requirement-extended.aspx). Machines should continue update normally with this month’s patches. Virtual Administrator is working on a blog to give guidance on the installation of KB2919355 soon.
This is a Security Advisory (not a Bulletin). Security Advisories are issues that may not be classified as vulnerabilities and may not require a security bulletin.
