CVE-2003-0695 2 Openbsd, Redhat 3 Openssh, Enterprise Linux, Linux 2026-04-16 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-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-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-2004-0175 2 Openbsd, Redhat 2 Openssh, Enterprise Linux 2026-04-16 N/A
Directory traversal vulnerability in scp for OpenSSH before 3.4p1 allows remote malicious servers to overwrite arbitrary files. NOTE: this may be a rediscovery of CVE-2000-0992.
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-2001-0816 2 Openbsd, Redhat 2 Openssh, Linux 2026-04-16 N/A
OpenSSH before 2.9.9, when running sftp using sftp-server and using restricted keypairs, allows remote authenticated users to bypass authorized_keys2 command= restrictions using sftp commands.
CVE-2001-1029 2 Freebsd, Openbsd 2 Freebsd, Openssh 2026-04-16 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-2005-2797 1 Openbsd 1 Openssh 2026-04-16 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-2003-1562 1 Openbsd 1 Openssh 2026-04-16 N/A
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.
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-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-2003-0786 1 Openbsd 1 Openssh 2026-04-16 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-2003-0693 2 Openbsd, Redhat 3 Openssh, Enterprise Linux, Linux 2026-04-16 N/A
A "buffer management error" in buffer_append_space of buffer.c for OpenSSH before 3.7 may allow remote attackers to execute arbitrary code by causing an incorrect amount of memory to be freed and corrupting the heap, a different vulnerability than CVE-2003-0695.
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-2000-0143 2 Openbsd, Ssh 2 Openssh, Ssh 2026-04-16 N/A
The SSH protocol server sshd allows local users without shell access to redirect a TCP connection through a service that uses the standard system password database for authentication, such as POP or FTP.
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-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-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-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-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.
