A day after Apple and Google rolled out urgent security updates, Microsoft has pushed software fixes as part of its monthly Patch Tuesday release cycle to plug 66 security holes affecting Windows and other components such as Azure, Office, BitLocker, and Visual Studio, including an actively exploited zero-day in its MSHTML Platform that came to light last week.
Of the 66 flaws, three are rated Critical, 62 are rated Important, and one is rated Moderate in severity. This is aside from the 20 vulnerabilities in the Chromium-based Microsoft Edge browser that the company addressed since the start of the month.
