  • Report on the Third Static Analysis Tool Exposition (SATE 2010)
    Special Publication 500-283 Report on the Third Static Analysis Tool Exposition (SATE 2010) Editors: Vadim Okun Aurelien Delaitre Paul E. Black Software and Systems Division Information Technology Laboratory National Institute of Standards and Technology Gaithersburg, MD 20899 October 2011 U.S. Department of Commerce John E. Bryson, Secretary National Institute of Standards and Technology Patrick D. Gallagher, Under Secretary for Standards and Technology and Director Abstract: The NIST Software Assurance Metrics And Tool Evaluation (SAMATE) project conducted the third Static Analysis Tool Exposition (SATE) in 2010 to advance research in static analysis tools that find security defects in source code. The main goals of SATE were to enable empirical research based on large test sets, encourage improvements to tools, and promote broader and more rapid adoption of tools by objectively demonstrating their use on production software. Briefly, participating tool makers ran their tool on a set of programs. Researchers led by NIST performed a partial analysis of tool reports. The results and experiences were reported at the SATE 2010 Workshop in Gaithersburg, MD, in October, 2010. The tool reports and analysis were made publicly available in 2011. This special publication consists of the following three papers. “The Third Static Analysis Tool Exposition (SATE 2010),” by Vadim Okun, Aurelien Delaitre, and Paul E. Black, describes the SATE procedure and provides observations based on the data collected. The other two papers are written by participating tool makers. “Goanna Static Analysis at the NIST Static Analysis Tool Exposition,” by Mark Bradley, Ansgar Fehnker, Ralf Huuck, and Paul Steckler, introduces Goanna, which uses a combination of static analysis with model checking, and describes its SATE experience, tool results, and some of the lessons learned in the process.

    Masaryk University Faculty}w¡¢£¤¥¦§¨ of Informatics!"#$%&'()+,-./012345<yA| Automatic Bug-finding Techniques for Large Software Projects Ph.D. Thesis Jiri Slaby Brno, 2013 Revision 159 Supervisor: prof. RNDr. Antonín Kučera, PhD. Co-supervisor: assoc. prof. RNDr. Jan Strejček, PhD. ii Copyright c Jiri Slaby, 2013 All rights reservedtož to ja iii iv Abstract This thesis studies the application of contemporary automatic bug-finding techniques to large software projects. As they tend to be complex systems, there is a call for efficient analyzers that can exercise such projects without generating too many false positives. To fulfill these requirements, this thesis aims at the static analysis with the primary focus at techniques like the abstract interpretation and symbolic execution. Since their introduction in 1970’s, their applicability is increasing thanks to current fast processors and further improvements of the techniques. The thesis summarizes the current state of the art of chosen techniques implemented in the current static analyzers. Further, we discuss some large code bases which can be used as a test-bed for the techniques. Finally, we choose the Linux kernel. On the top of the explored state of the art, we de- velop our own techniques. We present the framework Stanse which utilizes the abstract interpretation and has no issues with handling the Linux kernel. The framework also prunes false positives resulting from some checkers. The pruning method is based on the pattern matching, but it turns out to be weak. Hence we subsequently try to improve the situation by the symbolic execution. For that purpose we use an executor called Klee in our new tool Symbiotic.

  • How Developers Engage with Static Analysis Tools in Different Contexts
    Noname manuscript No. (will be inserted by the editor) How Developers Engage with Static Analysis Tools in Different Contexts Carmine Vassallo · Sebastiano Panichella · Fabio Palomba · Sebastian Proksch · Harald C. Gall · Andy Zaidman This is an author-generated version. The final publication will be available at Springer. Abstract Automatic static analysis tools (ASATs) are instruments that sup- port code quality assessment by automatically detecting defects and design issues. Despite their popularity, they are characterized by (i) a high false positive rate and (ii) the low comprehensibility of the generated warnings. However, no prior studies have investigated the usage of ASATs in different development contexts (e.g., code reviews, regular development), nor how open source projects integrate ASATs into their workflows. These perspectives are paramount to improve the prioritization of the identified warnings. To shed light on the actual ASATs usage practices, in this paper we first survey 56 developers (66% from industry and 34% from open source projects) and inter- view 11 industrial experts leveraging ASATs in their workflow with the aim of understanding how they use ASATs in different contexts. Furthermore, to in- vestigate how ASATs are being used in the workflows of open source projects, we manually inspect the contribution guidelines of 176 open-source systems and extract the ASATs' configuration and build files from their corresponding GitHub repositories. Our study highlights that (i) 71% of developers do pay attention to different warning categories depending on the development con- text; (ii) 63% of our respondents rely on specific factors (e.g., team policies and composition) when prioritizing warnings to fix during their programming; and (iii) 66% of the projects define how to use specific ASATs, but only 37% enforce their usage for new contributions.
