On the Analysis of Byte-Granularity Heap Randomization

Heap randomization, in general, has been a well-trodden area; however, the efficacy of byte-granularity randomization has never been fully explored as misalignment raises various concerns. Modern heap exploits often abuse the determinism in word alignment, and modern CPU architecture better supports unaligned access (since Nehalem). Based on such new developments, we conduct an in-depth analysis o...
