New Linux/Mac vulnerability GHOST... We are looking into a new Linux vulnerability today. If you aren't aware all Mac operating systems are now built on Linux technology so this means your Mac could be affected. There is a vulnerability that is being called GHOST because it allows a hacker to remotely take complete control of a victim's system without having any prior knowledge of system credentials. It is a buffer overflow vulnerability that can be triggered both remotely and locally. Look for a new update from Linux / Apple in the coming days to protect your system.UPDATE: This hole exists in any Linux system that was built with glibc-2.2, which was released on November 10, 2000. We will be looking into whether the current MacOS' use this kernel.
