Some people have noted a lack of a CVE number here.. Antoino Sanso was
a super guy and reported this problem to us directly. At his request,
we delayed release of the fix until OpenSSL released their stuff.
The actual high severity problem in OpenSSL is not present in
LibreSSL, Nor was the CVE in question assigned to LibreSSL. - So no
CVE.

We are very happy to fix problems and make a better Codebase. However
I at least will express my doubts about the benefits of the CVE system
to the community - When the CVE is not assigned to LibreSSL, We
receive no notification of it, while the project it is assigned to
gets advance notification and controls the release timing. As such
without the CVE being
assigned to LibreSSL, and us getting a say in the timing of the
release of the information and when to roll releases, I do
not see a benefit to us or the community of our promoting someone
else's invoice numbers, when we don't get a say in when stuff is
released.
