CVE-2002-0640 1 Openbsd 1 Openssh 2025-04-03 10.0 HIGH N/A
Buffer overflow in sshd in OpenSSH 2.3.1 through 3.3 may allow remote attackers to execute arbitrary code via a large number of responses during challenge response authentication when OpenBSD is using PAM modules with interactive keyboard authentication (PAMAuthenticationViaKbdInt).
CVE-2002-0639 1 Openbsd 1 Openssh 2025-04-03 10.0 HIGH 9.8 CRITICAL
Integer overflow in sshd in OpenSSH 2.9.9 through 3.3 allows remote attackers to execute arbitrary code during challenge response authentication (ChallengeResponseAuthentication) when OpenSSH is using SKEY or BSD_AUTH authentication.
CVE-2003-0695 1 Openbsd 1 Openssh 2025-04-03 7.5 HIGH N/A
Multiple "buffer management errors" in OpenSSH before 3.7.1 may allow attackers to cause a denial of service or execute arbitrary code using (1) buffer_init in buffer.c, (2) buffer_free in buffer.c, or (3) a separate function in channels.c, a different vulnerability than CVE-2003-0693.
CVE-2003-0682 1 Openbsd 1 Openssh 2025-04-03 7.5 HIGH N/A
"Memory bugs" in OpenSSH 3.7.1 and earlier, with unknown impact, a different set of vulnerabilities than CVE-2003-0693 and CVE-2003-0695.
CVE-2006-0883 2 Freebsd, Openbsd 2 Freebsd, Openssh 2025-04-03 5.0 MEDIUM N/A
OpenSSH on FreeBSD 5.3 and 5.4, when used with OpenPAM, does not properly handle when a forked child process terminates during PAM authentication, which allows remote attackers to cause a denial of service (client connection refusal) by connecting multiple times to the SSH server, waiting for the password prompt, then disconnecting.
CVE-2001-1459 1 Openbsd 1 Openssh 2025-04-03 7.5 HIGH N/A
OpenSSH 2.9 and earlier does not initiate a Pluggable Authentication Module (PAM) session if commands are executed with no pty, which allows local users to bypass resource limits (rlimits) set in pam.d.
CVE-2003-0190 3 Openbsd, Openpkg, Siemens 6 Openssh, Openpkg, Scalance X204rna and 3 more 2025-04-03 5.0 MEDIUM N/A
OpenSSH-portable (OpenSSH) 3.6.1p1 and earlier with PAM support enabled immediately sends an error message when a user does not exist, which allows remote attackers to determine valid usernames via a timing attack.
CVE-2001-1380 1 Openbsd 1 Openssh 2025-04-03 7.5 HIGH N/A
OpenSSH before 2.9.9, while using keypairs and multiple keys of different types in the ~/.ssh/authorized_keys2 file, may not properly handle the "from" option associated with a key, which could allow remote attackers to login from unauthorized IP addresses.
CVE-2003-0386 1 Openbsd 1 Openssh 2025-04-03 7.5 HIGH N/A
OpenSSH 3.6.1 and earlier, when restricting host access by numeric IP addresses and with VerifyReverseMapping disabled, allows remote attackers to bypass "from=" and "user@host" address restrictions by connecting to a host from a system whose reverse DNS hostname contains the numeric IP address.
CVE-2001-1585 1 Openbsd 1 Openssh 2025-04-03 6.8 MEDIUM N/A
SSH protocol 2 (aka SSH-2) public key authentication in the development snapshot of OpenSSH 2.3.1, available from 2001-01-18 through 2001-02-08, does not perform a challenge-response step to ensure that the client has the proper private key, which allows remote attackers to bypass authentication as other users by supplying a public key from that user's authorized_keys file.
CVE-2002-0765 1 Openbsd 2 Openbsd, Openssh 2025-04-03 7.5 HIGH N/A
sshd in OpenSSH 3.2.2, when using YP with netgroups and under certain conditions, may allow users to successfully authenticate and log in with another user's password.
CVE-2000-0999 1 Openbsd 1 Openssh 2025-04-03 10.0 HIGH N/A
Format string vulnerabilities in OpenBSD ssh program (and possibly other BSD-based operating systems) allow attackers to gain root privileges.
CVE-2006-0225 1 Openbsd 1 Openssh 2025-04-03 4.6 MEDIUM N/A
scp in OpenSSH 4.2p1 allows attackers to execute arbitrary commands via filenames that contain shell metacharacters or spaces, which are expanded twice.
CVE-2005-2797 1 Openbsd 1 Openssh 2025-04-03 5.0 MEDIUM N/A
OpenSSH 4.0, and other versions before 4.2, does not properly handle dynamic port forwarding ("-D" option) when a listen address is not provided, which may cause OpenSSH to enable the GatewayPorts functionality.
CVE-2001-1029 2 Freebsd, Openbsd 2 Freebsd, Openssh 2025-04-03 2.1 LOW N/A
libutil in OpenSSH on FreeBSD 4.4 and earlier does not drop privileges before verifying the capabilities for reading the copyright and welcome files, which allows local users to bypass the capabilities checks and read arbitrary files by specifying alternate copyright or welcome files.
CVE-2003-0786 1 Openbsd 1 Openssh 2025-04-03 10.0 HIGH N/A
The SSH1 PAM challenge response authentication in OpenSSH 3.7.1 and 3.7.1p1, when Privilege Separation is disabled, does not check the result of the authentication attempt, which can allow remote attackers to gain privileges.
CVE-2001-1507 1 Openbsd 1 Openssh 2025-04-03 7.5 HIGH N/A
OpenSSH before 3.0.1 with Kerberos V enabled does not properly authenticate users, which could allow remote attackers to login unchallenged.
CVE-2001-1382 1 Openbsd 1 Openssh 2025-04-03 5.0 MEDIUM N/A
The "echo simulation" traffic analysis countermeasure in OpenSSH before 2.9.9p2 sends an additional echo packet after the password and carriage return is entered, which could allow remote attackers to determine that the countermeasure is being used.
CVE-2000-0525 1 Openbsd 1 Openssh 2025-04-03 10.0 HIGH N/A
OpenSSH does not properly drop privileges when the UseLogin option is enabled, which allows local users to execute arbitrary commands by providing the command to the ssh daemon.
CVE-2000-0217 2 Openbsd, Ssh 3 Openssh, Ssh, Ssh2 2025-04-03 5.1 MEDIUM N/A
The default configuration of SSH allows X forwarding, which could allow a remote attacker to control a client's X sessions via a malicious xauth program.
