HardenedBSD Completes Strong ASLR Implementation
New submitter HardenedBSD writes: A relatively new fork of FreeBSD, HardenedBSD, has completed its Address Space Layout Randomization (ASLR) feature. Without ASLR, applications are loaded into memory in a deterministic manner. An attacker who knows where a vulnerability lies in memory can reliably exploit that vulnerability to manipulate the application into doing the attacker's bidding. ASLR removes the determinism, making it so that even if an attacker knows that a vulnerability exists, he doesn't know where that vulnerability lies in memory. HardenedBSD's particular implementation of ASLR is the strongest form ever implemented in any of the BSDs. The next step is to update documentation and submit updates to the patches they have already submitted upstream to FreeBSD. ASLR is the first step in a long list of exploit mitigation technologies HardenedBSD plans to implement.Read more of this story at Slashdot.
