Upgrade Debian:11

to version 1:5.6p1-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream openssh
package and not the openssh
package as distributed by Debian
.
See How to fix?
for Debian:11
relevant fixed versions and status.
The auth_parse_options function in auth-options.c in sshd in OpenSSH before 5.7 provides debug messages containing authorized_keys command options, which allows remote authenticated users to obtain potentially sensitive information by reading these messages, as demonstrated by the shared user account required by Gitolite. NOTE: this can cross privilege boundaries because a user account may intentionally have no shell or filesystem access, and therefore may have no supported way to read an authorized_keys file in its own home directory.
