sshd in OpenSSH 3.6.1p2 and earlier, when PermitRootLogin is disabled
and using PAM keyboard-interactive authentication, does not insert a
delay after a root login attempt with the correct password, which
makes it easier for remote attackers to use timing differences to
determine if the password step of a multi-step authentication is
successful, a different vulnerability than CVE-2003-0190.
The risks associated with fixing this bug are greater than the low severity security risk. We therefore currently have no plans to fix this flaw in Red Hat Enterprise Linux 2.1 and 3 which is in maintenance mode.
