CVE-2012-0814

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.
