The golang.org/x/crypto/ssh package before

server in certain circumstances involving AddHostKey.
Author | Note |
---|---|
jdstrand | snapd contains an embedded copy of golang-go.crypto lxd in 18.04 LTS and earlier contains an embedded copy of golang-go.crypto |
mdeslaur | snapd and lxd only use the terminal sub-package, not the ssh part of golang-go.crypto, so they are not vulnerable |
