title: Regular Expression to find CVE Matches
body: <p>I am pretty new to the concept of regex and so I am hoping an expert user can help me craft the right expression to find all the matches in a string.  I have a string that represents a lot of support information in it for vulnerabilities data.  In that string are a series of CVE references in the format: CVE-2015-4000.  Can anyone provide me a sample regex on finding all occurrences of that ?  obviously, the numeric part of that changes throughout the string...</p>
