Classification of PVS-Studio warnings according to the Common Weakness Enumeration (CWE)

The Common Weakness Enumeration (CWE) is a category system for software weaknesses and vulnerabilities. It is sustained by a community project with the goals of understanding flaws in software and creating automated tools that can be used to identify, fix, and prevent those flaws.

CCR (Coverage Claims Representation) for PVS-Studio is available here.
