Notes
Net::Server was already fixed in 0.87-1, although the changelog doesn't mention
the security implication, which was noticed later. I've verified both fixes
are identical
but DSA-1122 thinks it was fixed in 0.89-1, so mark that version to make
scripts happy (at time of writing, 0.90-1 is in testing)
