Java and Scala's Type Systems are Unsound: The Existential Crisis of Null Pointers

Nada Amin

We present short programs that demonstrate the unsoundness of Java and Scala’s current type systems. In particular, these programs provide parametrically polymorphic functions that can turn any type into any type without (down)casting. Fortunately, paramet ...

Code-Pointer Integrity

George Candea, Mathias Josef Payer, Volodymyr Kuznetsov

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 ...

Spores: A Type-Based Foundation for Closures in the Age of Concurrency and Distribution

Martin Odersky, Philipp Haller

Functional programming (FP) is regularly touted as the way forward for bringing parallel, concurrent, and distributed programming to the mainstream. The popularity of the rationale behind this viewpoint (immutable data transformed by function application) ...

Miniboxing: Improving the Speed to Code Size Tradeoff in Parametric Polymorphism Translations

Martin Odersky, Vlad Ureche, Cristian Talau

Parametric polymorphism enables code reuse and type safety. Underneath the uniform interface exposed to programmers, however, its low level implementation has to cope with inherently non-uniform data: value types of different sizes and semantics (bytes, in ...

An Embedded Query Language in Scala

Amir Shaikhha

In this thesis we address the problem of integrating general purpose programming languages with relational databases. An approach to solving this problem is using raw strings to represent SQL statements. This approach leads to runtime errors and security v ...

Alternating Control Flow Reconstruction

Johannes Kinder

Unresolved indirect branch instructions are a major obstacle for statically reconstructing a control flow graph (CFG) from machine code. If static analysis cannot compute a precise set of possible targets for a branch, the necessary conservative over-appro ...

Towards Static Analysis of Virtualization-Obfuscated Binaries

Johannes Kinder

Virtualization-obfuscation protects a program from manual or automated analysis by compiling it into bytecode for a randomized virtual architecture and attaching a corresponding interpreter. Static analysis appears to be helpless on such programs, where on ...

System and method for in-vivo multi-path analysis of binary software

George Candea, Vitaly Chipounov, Volodymyr Kuznetsov

A system and method for in-vivo multi-path analysis and testing of binary software including binary device drivers is disclosed. The system and method may be used to test a binary software system and may comprise a virtual machine, a symbolic execution eng ...

Static Analysis of x86 Executables

Johannes Kinder

This dissertation is concerned with static analysis of binary executables in a theoretically well-founded, sound, yet practical way. The major challenge is the reconstruction of a correct control flow graph in presence of indirect jumps, pointer arithmetic ...
