It's always nice to fully explain things in the commit message,
as you have done here - not only does it make the reviewer's job
easier today, but down the road, it will make it much easier to
answer what the CVE was all about and who is impacted (or more
specifically, that default installation is NOT impacted).  Thanks
for taking the time to write it up.

ACK.  And let's get this in, so distros can start backporting
the CVE fix for the sake of those people who ARE impacted.
