Today, I saw this in the news. I'm hesitant to install the fix, because I've heard it would slow down IO 50%, which is not acceptable for me.
But a guy said that the flaw allows JavaScript in the browser steal your information. Is this true? Worst case scenario for me is that any website I visit could run some dangerous JS that takes conrol of my PC. Only that would get me to install the fix.
I am not familiar with security, I just want to know actually how it affect us in the real world.
