openssh/openssh-8.4p1-vendordir.patch
Marcus Meissner 3f6eda5c88 - Update to openssh 9.9p1: 
* No changes for askpass, see main package changelog for
    details.

- Update to openssh 9.9p1:
  = Future deprecation notice
  * OpenSSH plans to remove support for the DSA signature algorithm
    in early 2025. This release disables DSA by default at compile
    time. DSA, as specified in the SSHv2 protocol, is inherently
    weak - being limited to a 160 bit private key and use of the
    SHA1 digest. Its estimated security level is only 80 bits
    symmetric equivalent.
    OpenSSH has disabled DSA keys by default since 2015 but has
    retained run-time optional support for them. DSA was the only
    mandatory-to-implement algorithm in the SSHv2 RFCs, mostly
    because alternative algorithms were encumbered by patents when
    the SSHv2 protocol was specified.
    This has not been the case for decades at this point and better
    algorithms are well supported by all actively-maintained SSH
    implementations. We do not consider the costs of maintaining
    DSA in OpenSSH to be justified and hope that removing it from
    OpenSSH can accelerate its wider deprecation in supporting
    cryptography libraries.
  = Potentially-incompatible changes
  * ssh(1): remove support for pre-authentication compression.
    OpenSSH has only supported post-authentication compression in
    the server for some years. Compression before authentication
    significantly increases the attack surface of SSH servers and
    risks creating oracles that reveal information about
    information sent during authentication.
