Since the regression was introduced via a DSA, we might address this
regression trough af follow-up DSA:

s/UNRELEASED/wheezy-security/ and urgency=high set or respectively
jessie-security for the second one.

With the above changes please go ahead with your upload to
security-master.

Thanks for your work and pinging us about the regression.
