Cyber security research has produced numerous artificial diversity techniques such as address space layout randomization, heap randomization, instruction-set randomization, and instruction location randomization. To be most effective, these techniques must be high entropy and secure from information leakage which, in practice, is often difficult to achieve. Indeed, it has been ...

Normalized cross-correlation template matching is used as a detection method in many scientific domains. To be practical, template matching must scale to large datasets while handling ambiguity, uncertainty, and noisy data. We propose a novel approach based on Dempster-Shafer (DS) Theory and MapReduce parallelism. DS Theory addresses conflicts between data ...

The speed with which newly discovered software vulnerabilities are patched is a critical factor in mitigating the harm caused by subsequent exploits. Unfortunately, software vendors are often slow or unwilling to patch vulnerabilities, especially in embedded systems which frequently have no mechanism for updating factory-installed firmware. The situation is particularly ...

This article describes and evaluates DIG, a dynamic invariant generator that infers invariants from observed program traces, focusing on numerical and array variables. For numerical invariants, DIG supports both nonlinear equalities and inequalities of arbitrary degree defined over numerical program variables. For array invariants, DIG generates nested relations among multidimensional ...

Program invariants are important for defect detection, program verification, and program repair. However, existing techniques have limited support for important classes of invariants such as disjunctions, which express the semantics of conditional statements. We propose a method for generating disjunctive invariants over numerical domains, which are inexpressible using classical convex ...

Much initial research on automatic program repair has focused on experimental results to probe their potential to find patches and reduce development effort. Relatively less effort has been put into understanding the hows and whys of such approaches. For example, a critical assumption of the GenProg technique is that certain ...

Software bugs remain a compelling problem. Automated program repair is a promising approach for reducing cost, and many methods have recently demonstrated positive results. However, success on any particular bug is variable, as is the cost to find a repair. This paper focuses on generate-and-validate repair methods that enumerate candidate ...

The abundance of defects in existing software systems is unsustainable. Addressing them is a dominant cost of software maintenance, which in turn dominates the life cycle cost of a system. Recent research has made significant progress on the problem of automatic program repair, using techniques such as evolutionary computation, instrumentation ...

In this keynote address I survey recent success and momentum in the subfield of automated program repair. I also encourage the search-based software engineering community to rise to various challenges and opportunities associated with test oracle generation, large-scale human studies, and reproducible research through benchmarks. I discuss recent advances in ...

Identifying and fixing defects is a crucial and expensive part of the software lifecycle. Measuring the quality of bug-fixing patches is a difficult task that affects both functional correctness and the future maintainability of the code base. Recent research interest in automatic patch generation makes a systematic understanding of patch ...

Full text available: PDFPDF
Evolutionary computation is a promising technique for automating time-consuming and expensive software maintenance tasks, including bug repair. The success of this approach, however, depends at least partially on the choice of representation, fitness function, and operators. Previous work on evolutionary software repair has employed different approaches, but they have not ...

There are more bugs in real-world programs than human programmers can realistically address. This paper evaluates two research questions: ``What fraction of bugs can be repaired automatically?'' and ``How much does it cost to repair a bug automatically?'' In previous work, we presented GenProg, which uses genetic programming to repair ...

Dynamic invariant analysis identifies likely properties over variables from observed program traces. These properties can aid programmers in refactoring, documenting, and debugging tasks by making dynamic patterns visible statically. Two useful forms of invariants involve relations among polynomials over program variables and relations among array variables. Current dynamic analysis methods ...
