CVE-2005-2666 2 Openbsd, Redhat 2 Openssh, Enterprise Linux 2026-04-16 N/A
SSH, as implemented in OpenSSH before 4.0 and possibly other implementations, stores hostnames, IP addresses, and keys in plaintext in the known_hosts file, which makes it easier for an attacker that has compromised an SSH user's account to generate a list of additional targets that are more likely to have the same password or key.
CVE-2001-0361 2 Openbsd, Ssh 2 Openssh, Ssh 2026-04-16 N/A
Implementations of SSH version 1.5, including (1) OpenSSH up to version 2.3.0, (2) AppGate, and (3) ssh-1 up to version 1.2.31, in certain configurations, allow a remote attacker to decrypt and/or alter traffic via a "Bleichenbacher attack" on PKCS#1 version 1.5.
CVE-2000-0217 2 Openbsd, Ssh 3 Openssh, Ssh, Ssh2 2026-04-16 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.
CVE-2001-0872 3 Openbsd, Redhat, Suse 3 Openssh, Linux, Suse Linux 2026-04-16 N/A
OpenSSH 3.0.1 and earlier with UseLogin enabled does not properly cleanse critical environment variables such as LD_PRELOAD, which allows local users to gain root privileges.
CVE-2001-1507 1 Openbsd 1 Openssh 2026-04-16 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-2000-1169 1 Openbsd 1 Openssh 2026-04-16 N/A
OpenSSH SSH client before 2.3.0 does not properly disable X11 or agent forwarding, which could allow a malicious SSH server to gain access to the X11 display and sniff X11 events, or gain access to the ssh-agent.
CVE-2001-1382 1 Openbsd 1 Openssh 2026-04-16 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-2004-2069 2 Openbsd, Redhat 2 Openssh, Enterprise Linux 2026-04-16 N/A
sshd.c in OpenSSH 3.6.1p2 and 3.7.1p2 and possibly other versions, when using privilege separation, does not properly signal the non-privileged process when a session has been terminated after exceeding the LoginGraceTime setting, which leaves the connection open and allows remote attackers to cause a denial of service (connection consumption).
CVE-2004-2760 1 Openbsd 1 Openssh 2026-04-16 N/A
sshd in OpenSSH 3.5p1, when PermitRootLogin is disabled, immediately closes the TCP connection after a root login attempt with the correct password, but leaves the connection open after an attempt with an incorrect password, which makes it easier for remote attackers to guess the password by observing the connection state, a different vulnerability than CVE-2003-0190. NOTE: it could be argued that in most environments, this does not cross privilege boundaries without requiring leverage of a separate vulnerability.
CVE-2006-0883 2 Freebsd, Openbsd 2 Freebsd, Openssh 2026-04-16 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-2001-1585 1 Openbsd 1 Openssh 2026-04-16 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-2002-0640 2 Openbsd, Redhat 3 Openssh, Enterprise Linux, Linux 2026-04-16 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-2005-2798 2 Openbsd, Redhat 2 Openssh, Enterprise Linux 2026-04-16 N/A
sshd in OpenSSH before 4.2, when GSSAPIDelegateCredentials is enabled, allows GSSAPI credentials to be delegated to clients who log in using non-GSSAPI methods, which could cause those credentials to be exposed to untrusted users or hosts.
CVE-2003-0190 4 Openbsd, Openpkg, Redhat and 1 more 8 Openssh, Openpkg, Enterprise Linux and 5 more 2026-04-16 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-2000-0992 2 Openbsd, Ssh 2 Openssh, Ssh 2026-04-16 N/A
Directory traversal vulnerability in scp in sshd 1.2.xx allows a remote malicious scp server to overwrite arbitrary files via a .. (dot dot) attack.
CVE-2000-0999 1 Openbsd 1 Openssh 2026-04-16 N/A
Format string vulnerabilities in OpenBSD ssh program (and possibly other BSD-based operating systems) allow attackers to gain root privileges.
CVE-1999-1010 1 Openbsd 1 Openssh 2026-04-16 N/A
An SSH 1.2.27 server allows a client to use the "none" cipher, even if it is not allowed by the server policy.
CVE-2004-1653 1 Openbsd 1 Openssh 2026-04-16 N/A
The default configuration for OpenSSH enables AllowTcpForwarding, which could allow remote authenticated users to perform a port bounce, when configured with an anonymous access program such as AnonCVS.
CVE-2002-0639 1 Openbsd 1 Openssh 2026-04-16 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-2001-1459 1 Openbsd 1 Openssh 2026-04-16 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.
