"The latest release of Google's Android mobile operating system has finally been properly fortified with an industry-standard defense. It's designed to protect end users against hack attacks that install malware on handsets. In an analysis published Monday, security researcher Jon Oberheide said Android version 4.1, aka Jelly Bean, is the first version of the Google-developed OS to properly implement a protection known as address space layout randomization. ASLR, as it's more often referred to, randomizes the memory locations for the library, stack, heap, and most other OS data structures. As a result, hackers who exploit memory corruption bugs that inevitably crop up in complex pieces of code are unable to know in advance where their malicious payloads will be loaded. When combined with a separate defense known as data execution prevention, ASLR can effectively neutralize such attacks."
