CVE-2004-2069 2 Openbsd, Redhat 2 Openssh, Enterprise Linux 2025-04-03 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-2005-2798 2 Openbsd, Redhat 2 Openssh, Enterprise Linux 2025-04-03 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-2005-2797 1 Openbsd 1 Openssh 2025-04-03 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-2002-0640 2 Openbsd, Redhat 3 Openssh, Enterprise Linux, Linux 2025-04-03 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-2006-0883 2 Freebsd, Openbsd 2 Freebsd, Openssh 2025-04-03 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-2006-0225 2 Openbsd, Redhat 2 Openssh, Enterprise Linux 2025-04-03 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-2001-1507 1 Openbsd 1 Openssh 2025-04-03 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-2001-1585 1 Openbsd 1 Openssh 2025-04-03 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-2000-1169 1 Openbsd 1 Openssh 2025-04-03 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-2002-0083 9 Conectiva, Engardelinux, Immunix and 6 more 11 Linux, Secure Linux, Immunix and 8 more 2025-04-03 9.8 Critical
Off-by-one error in the channel code of OpenSSH 2.0 through 3.0.2 allows local users or remote malicious servers to gain privileges.
CVE-2001-0529 1 Openbsd 1 Openssh 2025-04-03 N/A
OpenSSH version 2.9 and earlier, with X forwarding enabled, allows a local attacker to delete any file named 'cookies' via a symlink attack.
CVE-2001-0872 3 Openbsd, Redhat, Suse 3 Openssh, Linux, Suse Linux 2025-04-03 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-1999-1010 1 Openbsd 1 Openssh 2025-04-03 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-2001-1029 2 Freebsd, Openbsd 2 Freebsd, Openssh 2025-04-03 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-2000-0217 2 Openbsd, Ssh 3 Openssh, Ssh, Ssh2 2025-04-03 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-2000-0525 1 Openbsd 1 Openssh 2025-04-03 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-2001-1459 1 Openbsd 1 Openssh 2025-04-03 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-2004-2760 1 Openbsd 1 Openssh 2025-04-03 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-2023-51767 3 Fedoraproject, Openbsd, Redhat 3 Fedora, Openssh, Enterprise Linux 2024-11-21 7.0 High
OpenSSH through 9.6, when common types of DRAM are used, might allow row hammer attacks (for authentication bypass) because the integer value of authenticated in mm_answer_authpassword does not resist flips of a single bit. NOTE: this is applicable to a certain threat model of attacker-victim co-location in which the attacker has user privileges.
CVE-2023-51385 3 Debian, Openbsd, Redhat 5 Debian Linux, Openssh, Enterprise Linux and 2 more 2024-11-21 6.5 Medium
In ssh in OpenSSH before 9.6, OS command injection might occur if a user name or host name has shell metacharacters, and this name is referenced by an expansion token in certain situations. For example, an untrusted Git repository can have a submodule with shell metacharacters in a user name or host name.
