+ <p>cloud-init release 20.4.1 is now available. This is a hotfix
+ release, that contains a single patch to address a security issue in
+ cloud-init 20.4.</p>
+
+ <p>Briefly, for users who provide more than one unique SSH key to
+ cloud-init and have a shared AuthorizedKeysFile configured in
+ sshd_config, cloud-init 20.4 started writing all of these keys to such a
+ file, granting all such keys SSH access as root.</p>
+
+ <p>It's worth restating this implication: if you are using the default
+ AuthorizedKeysFile setting in /etc/ssh/sshd_config, as most will be,
+ then you are _not_ affected by this issue.</p>
