This version contains a fix for CVE-2022-27191 (not sure if it affects us).
From the golang mailing list:
Hello gophers,
Version v0.0.0-20220315160706-3147a52a75dd of golang.org/x/crypto/ssh implements
client authentication support for signature algorithms based on SHA-2 for use with
existing RSA keys.
Previously, a client would fail to authenticate with RSA keys to servers that
reject signature algorithms based on SHA-1. This includes OpenSSH 8.8 by default
and—starting today March 15, 2022 for recently uploaded keys.
We are providing this announcement as the error (“ssh: unable to authenticate”)
might otherwise be difficult to troubleshoot.
Version v0.0.0-20220314234659-1baeb1ce4c0b (included in the version above) also
fixes a potential security issue where an attacker could cause a crash in a
golang.org/x/crypto/ssh server under these conditions:
- The server has been configured by passing a Signer to ServerConfig.AddHostKey.
- The Signer passed to AddHostKey does not also implement AlgorithmSigner.
- The Signer passed to AddHostKey does return a key of type “ssh-rsa” from its PublicKey method.
Servers that only use Signer implementations provided by the ssh package are
unaffected. This is CVE-2022-27191.
Alla prossima,
Filippo for the Go Security team

Version v0.0.0-20200220183623-bac4c82f6975 of golang.org/x/crypto fixes a
vulnerability in the golang.org/x/crypto/ssh package which allowed peers to
cause a panic in SSH servers that accept public keys and in any SSH client.
An attacker can craft an ssh-ed25519 or sk-ssh-ed25519@openssh.com public
key, such that the library will panic when trying to verify a signature
with it. Clients can deliver such a public key and signature to any
golang.org/x/crypto/ssh server with a PublicKeyCallback, and servers can
deliver them to any golang.org/x/crypto/ssh client.
This issue was discovered and reported by Alex Gaynor, Fish in a Barrel,
and is tracked as CVE-2020-9283.

Includes 69ecbb4d6d
(forward-port of 8b5121be2f),
which fixes CVE-2020-7919:
- Panic in crypto/x509 certificate parsing and golang.org/x/crypto/cryptobyte
On 32-bit architectures, a malformed input to crypto/x509 or the ASN.1 parsing
functions of golang.org/x/crypto/cryptobyte can lead to a panic.
The malformed certificate can be delivered via a crypto/tls connection to a
client, or to a server that accepts client certificates. net/http clients can
be made to crash by an HTTPS server, while net/http servers that accept client
certificates will recover the panic and are unaffected.
Thanks to Project Wycheproof for providing the test cases that led to the
discovery of this issue. The issue is CVE-2020-7919 and Go issue golang.org/issue/36837.
