[Bug 2052328] Re: openssh-client encounters MAC algo issue with EL8

[Marc Deslauriers]

Hi,

Thanks for reporting this issue. I can't seem to reproduce it though
with Oracle Linux v8 running openssh-server-8.0p1-17.el8.x86_64 and an
Ubuntu 22.04 client running 1:8.9p1-3ubuntu0.6.

Could you perhaps give me a bit more details on how I could reproduce
this?

Thanks!

Title:
  openssh-client encounters MAC algo issue with EL8

Status in openssh package in Ubuntu:
  New

Bug description:
  Ubuntu 22.04 system connecting to an Oracle Linux v8 host.  The
  following error occurs regardless of the the MACs specified (or not)
  in sshd_config:

  Corrupted MAC on input.
  ssh_dispatch_run_fatal: Connection to XX.XX.XX.XX port 22: message authentication code incorrect

  Presumably, this may happen on any RHEL v8 variant. Note that
  connecting to Enterprise Linux v7 work as well as other Ubuntu hosts.
  Downgrading to previous version of openssh-client fixes issue.

  apt install openssh-client=1:8.9p1-3
