Applying flow-sensitive CQUAL to verify MINIX authorization check placement
We present the first use of flow-sensitive CQUAL to verify the placement of operating system authorization checks. Our analysis of MINIX 3 system servers and discovery of a non-exploitable Time-Of-Check/Time-Of-Use bug demonstrate the effectiveness of flow sensitive CQUAL and its advantage over earlier flow-insensitive versions. We also identify and suggest alternatives to current CQUAL usability features that encourage analysts to make omissions that cause the otherwise sound tool to produce false-negative results.
