- Update to openssh 9.6p1:
= Security
* ssh(1), sshd(8): implement protocol extensions to thwart the
so-called "Terrapin attack" discovered by Fabian Bäumer, Marcus
Brinkmann and Jörg Schwenk. This attack allows a MITM to effect a
limited break of the integrity of the early encrypted SSH transport
protocol by sending extra messages prior to the commencement of
encryption, and deleting an equal number of consecutive messages
immediately after encryption starts. A peer SSH client/server
would not be able to detect that messages were deleted.
* ssh-agent(1): when adding PKCS#11-hosted private keys while
specifying destination constraints, if the PKCS#11 token returned
multiple keys then only the first key had the constraints applied.
Use of regular private keys, FIDO tokens and unconstrained keys
are unaffected.
* ssh(1): if an invalid user or hostname that contained shell
metacharacters was passed to ssh(1), and a ProxyCommand,
LocalCommand directive or "match exec" predicate referenced the
user or hostname via %u, %h or similar expansion token, then
an attacker who could supply arbitrary user/hostnames to ssh(1)
could potentially perform command injection depending on what
quoting was present in the user-supplied ssh_config(5) directive.
= Potentially incompatible changes
* ssh(1), sshd(8): the RFC4254 connection/channels protocol provides
a TCP-like window mechanism that limits the amount of data that
can be sent without acceptance from the peer. In cases where this

- Enhanced SELinux functionality. Added Fedora patches:
* openssh-7.8p1-role-mls.patch
Proper handling of MLS systems and basis for other SELinux
improvements
* openssh-6.6p1-privsep-selinux.patch
Properly set contexts during privilege separation
* openssh-6.6p1-keycat.patch
Add ssh-keycat command to allow retrival of authorized_keys
on MLS setups with polyinstantiation
* openssh-6.6.1p1-selinux-contexts.patch
Additional changes to set the proper context during privilege
separation
* openssh-7.6p1-cleanup-selinux.patch
Various changes and putting the pieces together
For now we don't ship the ssh-keycat command, but we need the patch
for the other SELinux infrastructure
This change fixes issues like bsc#1214788, where the ssh daemon
needs to act on behalf of a user and needs a proper context for this
