Wow, why wasn't it patched sooner? At least it's now being patched by every Linux distribution. I currently use Debian, and they have released a fix/patch for this CopyFail bug, so I am safe. However, for anyone else who uses a Linux distribution that hasn't released a fix yet, you can remediate the vulnerability by blocking the socket on which this bug/vulnerability relies. The code to remediate the bug is in the blog post by Theori, who discovered the CopyFail bug, which I have provided below. Hopefully, all Linux distributions will fix/patch this bug sooner rather than later. Source CopyFail Redmidation
