Bad bug found in Microsoft browsing code

"Google has released details of a bug in Microsoft's browsing programs that would allow attackers to build websites that make the software crash.

Google researcher Ivan Fratric said the bug could, in some cases, allow attackers to hijack a victim's browser."

Google is really teasing Microsoft now with their Project Zero (this is the second bug they find in short order). I wonder if this is a reaction to Microsoft's very aggressive push to get people to set Edge as default browser.

All in all I guess it's still fair because they give MS 90 days warning to fix the things. Still, makes you wonder. Are Microsoft's new ways fast, independent and agile enough to get fixes out in good time?
