+
+backport of the following two upstream commits
+
+f3cbe43e28fe71427d41cfe3a17125b972710455
+bf944e3794eff5413f2df1ef37cddf96918c6bde
+
+CVE-2021-41617 failed to correctly initialise supplemental groups
+when executing an AuthorizedKeysCommand or AuthorizedPrincipalsCommand,
+where a AuthorizedKeysCommandUser or AuthorizedPrincipalsCommandUser
+directive has been set to run the command as a different user. Instead
+these commands would inherit the groups that sshd(8) was started with.
