This is primarily a bugfix release, and also addresses security issues.
sshd(8): Mitigate a potential denial-of-service attack against the system's
crypt(3) function via sshd(8).
sshd(8): Mitigate timing differences in password authentication that could
be used to discern valid from invalid account names when long passwords were
sent and particular password hashing algorithms are in use on the server.
ssh(1), sshd(8): Fix observable timing weakness in the CBC padding oracle
countermeasures.
ssh(1), sshd(8): Improve operation ordering of MAC verification for
Encrypt-then-MAC (EtM) mode transport MAC algorithms to verify the MAC
before decrypting any ciphertext.
sshd(8): (portable only) Ignore PAM environment vars when UseLogin=yes.
