I decided to merge these in CVE.  The correlating data was too close.
And given that the iDEFENSE advisory mentioned there were 2 arguments for
VerCompare(), there isn't much room for different issues.  There only
seems to be one patch coming from Verisign in this time frame.  Now,
iDefense might have mistakenly assumed this was a fix for their vuln -
research orgs sometimes do that - but still, there are other correlators.

In CVE, we'll frequently note - but otherwise dismiss - when vendors talk
about "a" vuln because there are frequently multiple issues.  Everybody
counts vulns differently, vendors least of all.  Though it is strange that
they say *they* discovered it.
