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
