A nil pointer dereference in the golang.org/x/crypto/ssh component through
v0.0.0-20201203163018-be400aefbc4c for Go allows remote attackers to cause
a denial of service against SSH servers.

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
