No, they chewed snots for years because there wasn’t a trivial and straightforward fix and exploit looked too “theoretically possible”. But some time ago(months? year?) some company showed them a working exploit, so they started to think how to actually fix the problem. All that time they kept all in secret so hackers wouldn’t know. But the fix had leaked, letting hackers to figure out what was the vulnerability in the first place, so snot-chewing was replaced with running-and-screaming. By now everything is fixed for those who cared to update\recompile. Something like that.
