For around two decades now, hackers have exploited the design of the memory management system used by Linux programs in order to take control of a target's computer. Now though researchers at Check Point have introduced a new security mechanism for Linux users called 'safe-linking' which means attackers will need more than one vulnerability in order to take over the program. Safe-Linking protects a simple data structure called a 'single-linked-list', this is a list of elements in which one element points at the next element and so on until the end of the list is reached. The safe-linking method masks… [Continue Reading]
