Jump over ASLR: Attacking Branch Predictors to Bypass ASLRD mitry EvtyushkinDepartment of Computer ScienceState University of New Yorkat PonomarevDepartment of Computer ScienceState University of New Yorkat Abu-GhazalehComputer Science andEngineering DepartmentUniversity of California, Address Space Layout Randomization (ASLR) is a widely-used technique that protects systems against a range of works by randomizing the offset of key program segmentsin virtual memory, making it difficult for an attacker to derivethe addresses of specific code objects and consequently redirectthe control flow to this code. In this paper, we develop an attackto derive kernel and user-level ASLR offset using a side-channelattack on the Branch target buffer (BTB).
