Improving systems software security through program analysis and instrumentation

Security and reliability bugs are prevalent in systems software. Systems code is often written in low-level languages like C/C++, which offer many benefits but also delegate memory management and type safety to programmers. This invites bugs that cause cra ...

High System-Code Security with Low Overhead

Jonas Benedict Wagner, George Candea, Volodymyr Kuznetsov, Johannes Kinder

Security vulnerabilities plague modern systems because writing secure systems code is hard. Promising approaches can retrofit security automatically via runtime checks that implement the desired security policy; these checks guard critical operations, like ...

Code-Pointer Integrity

George Candea, Volodymyr Kuznetsov, Mathias Josef Payer

Systems code is often written in low-level languages like C/C++, which offer many benefits but also delegate memory management to programmers. This invites memory safety bugs that attackers can exploit to divert control flow and compromise the system. Depl ...

Advantageous State Merging During Symbolic Analysis

George Candea, Stefan Bucur, Volodymyr Kuznetsov, Johannes Kinder

A determination is made regarding whether to merge two symbolic analysis states. A first state corresponds to a first path through a program to a program location and a second state corresponds to a second path through the program to the program location. ...

-Overify: Optimizing Programs for Fast Verification

Jonas Benedict Wagner, George Candea, Volodymyr Kuznetsov

Developers rely on automated testing and verification tools to gain confidence in their software. The input to such tools is often generated by compilers that have been designed to generate code that runs fast, not code that can be verified easily and quic ...

Efficient State Merging in Symbolic Execution

George Candea, Stefan Bucur, Volodymyr Kuznetsov, Johannes Kinder

Symbolic execution has proven to be a practical technique for building automated test case generation and bug finding tools. Nevertheless, due to state explosion, these tools still struggle to achieve scalability. Given a program, one way to reduce the num ...
