title = "Identifying arbitrary memory access vulnerabilities in privilege-separated software",
abstract = "Privilege separation is a widely used technique to secure complex software systems. With privilege separation, software components are divided into several partitions and these partitions can only communicate through limited interfaces. However, the interfaces still provide a channel for one partition to influence code in other partitions. As a result, certain memory access patterns can be leveraged by attackers to perform arbitrary memory access. We refer to this type of memory access errors by the acronym DUI (Dereference Under the Influence). In this paper, we present a systematic method to detect vulnerabilities leading to DUI through binary analysis, and to estimate the capability attackers can obtain through DUI exploits. The evaluation shows that our approach can accurately identify vulnerable code that leads to arbitrary memory access in real-world software components and programs, when they are transformed to privilege-separated designs.",
