Malicious javascript embeded in SVG - what it does?
You are correct that the SVG file has embedded javascript. SVG's are Vector graphic files which will draw a image in the browser based on the instructions inside the file. The SVG you found contains obfuscated javascript to hide what is actually going on.
At a glance from what I can see, it is a script to open a new browser window and load a new URL, so by itself, it is not dangerous, it all depends on what website it is redirecting you to, and what scripts are set to kick off when you reach the website.
So in short, it CAN harm your computer given the assumption that the site you're being redirected to is malicious.
I hope that helps.
