CVE-2007-2243 1 Openbsd 1 Openssh 2017-07-29 5.0 MEDIUM N/A
OpenSSH 4.6 and earlier, when ChallengeResponseAuthentication is enabled, allows remote attackers to determine the existence of user accounts by attempting to authenticate via S/KEY, which displays a different response if the user account exists, a similar issue to CVE-2001-1483.
