Today I have spent way too much time handling the copy.fail situation #copyfail

The persons who discovered it didn't notify the distribution security list, so no patched kernels was available for people to install when they released it.

But they did have time to write an exploit, and thought it was a good idea to distribute that on day one, before vendors had time to provide patches.

I'm not very impressed with xint.io, I guess it's the marketing department that runs the show.
