Google have released details about a critical but that affects Microsoft web browsers Internet Explorer and Edge. The as yet unpatched bug allows a specifically formatted webpage to crash the browsers and in certain conditions this could give someone control of the computer. The bug was discovered back in November 2016 by Google researchers and Microsoft informed of the problem at that time. In line with Googles policy this gives the software developers 90 days to fix the product and release a patch. As of today though no patch has yet been released by Microsoft so Google went public with the issue. They have not yet given details on the bug but it is not thought that any cases of criminals using it have yet been reported.
Users of Microsoft browsers who are worried about the bug could swap to an alternative browser until this is fixed by MS.
