openssh outdated by 8.2

[Hadmut Danisch]

Hi,

yeah, it's not yet a bug, but it will become a (security) bug within lifetime of 20.04 if not 'fixed'.

Currently openssh for Ubuntu 20.04 is still on 8.1p1, while upstream the version 8.2 has just been released:

https://lists.mindrot.org/pipermail/openssh-unix-announce/2020-February/000138.html

It comes with important security updates, e.g. not accepting SHA-1 for key generation/signature anymore, and using FIDO2/U2F-tokens as a second factor. Especially the latter significantly improves security and helps against stealing keys and hijacking machines.

It would be important (and nice) to have these improvements of security in Ubuntu 20.04.

It might not yet be seen as a security vulnerability, but it will probably become one soon.

Thanks

Hi Hadmut,
we had the same discussion over the weekend if 8.2 would be good to have in 20.04.

I subscribed cjwatson who usually does openssh updates to comment on his intentions in this regard.

I'm already working on this.

Ubuntu 20.04/focal was released with 8.2p1.
