UPDATED:
This is really the TSLSA-2001-0023 with the MD5 sums for the TSL 1.1
and 1.2 packages updated as we forgot to sign them in the proper way.
Problem description:
From the OpenSSH Security Advisory (adv.option):
Depending on the order of the user keys in ~/.ssh/authorized_keys2
sshd might fail to apply the source IP based access control
restriction (e.g. from="10.0.0.1") to the correct key.
Impact:
Users can circumvent the system policy and login from disallowed
source IP addresses.
Action:
We recommend that all systems with this package installed are upgraded.
