pam_krb5: Fix spoofing vulnerability
An adversary on the network can log in via ssh as any user by spoofing
the KDC. When the machine has a keytab installed the keytab is used to
verify the service ticket. However, without a keytab there is no way
for pam_krb5 to verify the KDC's response and get a TGT with the
password.
If both the password _and_ the KDC are controlled by an adversary, the
adversary can provide a password that the adversary's spoofed KDC will
return a valid tgt for. Currently, without a keytab, pam_krb5 is
vulnerable to this attack.

Fix this by making dump_savectx() a macro, so that savectx() is always

dumpsys()/minidumpsys().
This fixes stack unwinding for the panicking thread from arm64

ssh: Update to OpenSSH 9.3p1
This release fixes a number of security bugs and has minor new
features and bug fixes. Security fixes, from the release notes
(https://www.openssh.com/txt/release-9.3):
This release contains fixes for a security problem and a memory
safety problem. The memory safety problem is not believed to be
exploitable, but we report most network-reachable memory faults as
security bugs.
* ssh-add(1): when adding smartcard keys to ssh-agent(1) with the
per-hop destination constraints (ssh-add -h ...) added in OpenSSH
8.9, a logic error prevented the constraints from being
communicated to the agent. This resulted in the keys being added
without constraints. The common cases of non-smartcard keys and
keys without destination constraints are unaffected. This problem
was reported by Luci Stanescu.
* ssh(1): Portable OpenSSH provides an implementation of the
getrrsetbyname(3) function if the standard library does not
provide it, for use by the VerifyHostKeyDNS feature. A
specifically crafted DNS response could cause this function to
perform an out-of-bounds read of adjacent stack data, but this
condition does not appear to be exploitable beyond denial-of-
service to the ssh(1) client.
The getrrsetbyname(3) replacement is only included if the system's
standard library lacks this function and portable OpenSSH was not
compiled with the ldns library (--with-ldns). getrrsetbyname(3) is
only invoked if using VerifyHostKeyDNS to fetch SSHFP records. This
problem was found by the Coverity static analyzer.

If KASAN is configured this copying may also trigger false positives
