This document discusses Coverity's participation in the 2010 Software Assurance Technology Experiment (SATE). It summarizes that Coverity analyzed significantly more code in 2010 than 2009, including Chrome, Wireshark, and Dovecot. Coverity's tools are freely available to SATE researchers. The results found around 2300 total defects, with 1900 being high or medium impact. Only around 1% of defects were selected for SATE. It recommends establishing a defect catalog by thoroughly triaging one codebase per language. It also suggests improving Common Vulnerabilities and Exposures (CVE) triage and providing virtual machines to analyze code.
