This is a big can of worms CVE-wise, since there can be multiple ways to
fix a single issue. As a result, I've come to believe that you shouldn't
try to define a vulnerability exclusively in terms of its fix. In
practice within CVE, if a single fix addresses an already-public CVE-xyz
and a whole bunch of other things, then we (generally) keep the
already-public CVE as is, and assign a new CVE(s) to the "bunch of other
things" that are simultaneously addressed.
For example - in package XYZ, you might have both XSS and SQL injection,
where the XSS is fixed by input validation (say, by ensuring that a
numeric input is actually converted to a number). This fix will
inadvertently address SQL injection, but a different XSS fix - say, proper
encoding - would not.
This is one of those areas where we can't be completely consistent in CVE,
and the amount of available information directly affects how many CVEs get
assigned.
