A fatal error has been detected by Java

So, Minecraft was working about 2 months ago just fine, and then I went to start it up one day and I got this "A fatal error has been detected by Java" error and I have no way of fixing it. I've tried to find fixes and stuff, but It just keeps evading me. I left the error log in attachments, and I just want to know how to fix it. It keeps crashing right after I launch the game. I get the mojang logo, and then it goes back to the launcher with an error.
