CVE-2020-29652
Published: 17 December 2020
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 |
