Oreo Enhances ASLR Security Through Hardware-Software Co-Design
By
–
ASLR was deployed in operating systems like Windows & Linux, but w/i the last decade, its security flaws rendered it ineffective. As a software-hardware co-design mechanism, Oreo’s masking abilities could make ASLR more secure & reliable.

ASLR Vulnerabilities: Microarchitectural Attacks Threaten System Security
By
–
Address space layout randomization (ASLR) scatters program instructions in a computer’s memory to prevent leaking precious data. The problem: Hackers use microarchitectural side attacks to locate them. They can then use code-reuse attacks to steal passwords & alter systems — but

CSAIL’s Oreo Method Mitigates Address Space Attacks
By
–
CSAIL’s "Oreo" method mitigates these attacks by removing randomized bits of addresses that lead to a program’s instructions. Its "masked address space" re-maps code from these virtual addresses to fixed locations before they’re executed w/i the hardware.
