In Microsoft’s April security updates, the company released patches to address 66 vulnerabilities, 24 of which were rated critical. The vulnerabilities affect a variety of Microsoft products including Internet Explorer, Edge, Windows Visual Studio, ChakraCore, Microsoft Office, Adobe Flash, and its Malware Protection Engine.
