Notes
| 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 |
