Upstream bug report:

http://krbdev.mit.edu/rt/Ticket/Display.html?id=7152

And the upstream fix:

https://github.com/krb5/krb5/commit/c5be6209311d4a8f10fda37d0d3f876c1b33b77b

This only affects krb5 1.8 and higher, and only clients authorized to
create principals can trigger the bug (so requires administrative
privileges).
