Visible to the public Toward Precise and Accurate Descriptions of Weaknesses

Abstract:

MITRE's Common Weakness Enumeration (CWE) http://cwe.mitre.org/ is a list of several hundred classes of weakness that may be found in software. While it is a huge amount of progress over what was available a decade ago, there is still a lot of work to do. We propose some directions to significantly improve CWEs. These directions come from semantic templates, software fault patterns, and other work.

To motivate our proposal, we give examples of some ambiguities, gaps, and problems that we found while checking the SATE V Ockham Sound Analysis Criteria http://samate.nist.gov/SATE5OckhamCriteria.html Even "simple" CWEs, such as uninitialized variable, don't correspond well to the warning classes that static analysis tools produce. For instance does CWE-457: Use of Uninitialized Variable cover the case when just one field of a structure is not initialized before it is used? Or does that fall under a far-more-general CWEs, like CWE-824: Access of Uninitialized Pointer, CWE-665: Improper Initialization, CWE-824: Access of Uninitialized Pointer, or CWE-908: Use of Uninitialized Resource?
