The following section describes the tools we built to test the utilities. These tools include the fuzz (random character) generator, ptyjig (to test interactive utilities), and scripts to automate the testing process. Next, we will describe the tests we performed, giving the types of input we presented to the utilities. Results from the tests will follow along with an analysis of the results, including identification and classification of the program bugs that caused the crashes. The final section presents concluding remarks, including suggestions for avoiding the types of problems detected by our study and some commentary on the bugs we found. We include an Appendix with the user manual pages for fuzz and ptyjig.read more

Cognitive radio testing framework based on USRP
TL;DR: A flexible testing framework for CR devices implemented using the Universal Software Radio Peripheral (USRP) Software Defined Radio (SDR) platform is proposed and described, together with a case study on a commercially available device.

SymJEx: symbolic execution on the GraalVM
Sebastian Kloibhofer,Thomas Pointhuber,Maximilian Heisinger,Hanspeter Mössenböck,Lukas Stadler,David Leopoldseder +5 more
TL;DR: This paper presents a novel symbolic execution engine called SymJEx, implemented on top of the multi-language Java Virtual Machine GraalVM, which uses the Graal compiler's intermediate representation to derive and evaluate path conditions, allowingGraalVM users to leverage the engine to improve software quality.
Web application vulnerability detection using dynamic analysis with peneteration testing
TL;DR: Extensions to the Tainted Mode Model (TMM) are presented which allows inter module vulnerabilities detection and a new approach to vulnerability is presented.
Dynamic test generation for large binary programs
David Wagner,David Molnar +1 more
TL;DR: This thesis develops new methods for addressing the problem of software security bugs, shows that these methods scale to large commodity software, and lays the foundation for a service that makes automatic, effective security testing available at a modest cost per bug found.

Inputs from Hell: Generating Uncommon Inputs from Common Samples.
TL;DR: This work uses a context-free grammar to parse a set of sample input files that represent the program's common usage, and determines probabilities for individual grammar production as they occur during parsing the inputs to obtain inputs that are close to the samples.

On the criteria to be used in decomposing systems into modules
TL;DR: In this paper, the authors discuss modularization as a mechanism for improving the flexibility and comprehensibility of a system while allowing the shortening of its development time, and the effectiveness of modularization is dependent upon the criteria used in dividing the system into modules.

Letters to the editor: go to statement considered harmful
TL;DR: My considerations are that, although the programmer's activity ends when he has constructed a correct program, the process taking place under control of his program is the true subject matter of his activity, and that his intellectual powers are rather geared to master static relations and his powers to visualize processes evolving in time are relatively poorly developed.

Go to statement considered harmful
TL;DR: In form and content, Dijkstra's letter is similar to his 1965 paper, and the last few paragraphs underscore once again why the subject of structured programming stayed out of the mainstream of the data processing industry for so long.

Efficient learning of context-free grammars from positive structural examples
TL;DR: It is shown that the class of reversible context-free grammars can be identified in the limit frompositive samples of structural descriptions and there exists an efficient algorithm to identify them from positive samples ofStructural descriptions, where a structural description of a context- free grammar is an unlabelled derivation tree of the grammar.

Crisis and aftermath
TL;DR: Last November the Internet was infected with a worm program that eventually spread to thousands of machines, disrupting normal activities and Internet connectivity for many days.
