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-2005-2666 1 Openbsd 1 Openssh 2025-04-03 1.2 LOW 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-2002-0083 9 Conectiva, Engardelinux, Immunix and 6 more 11 Linux, Secure Linux, Immunix and 8 more 2025-04-03 10.0 HIGH 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-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-2001-0816 1 Openbsd 1 Openssh 2025-04-03 7.5 HIGH 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-2004-2760 1 Openbsd 1 Openssh 2025-04-03 6.8 MEDIUM 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-2006-0225 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-2000-0992 2 Openbsd, Ssh 2 Openssh, Ssh 2025-04-03 5.0 MEDIUM 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-2002-0575 1 Openbsd 1 Openssh 2025-04-03 7.5 HIGH N/A
Buffer overflow in OpenSSH before 2.9.9, and 3.x before 3.2.1, with Kerberos/AFS support and KerberosTgtPassing or AFSTokenPassing enabled, allows remote and local authenticated users to gain privileges.
CVE-2003-0693 1 Openbsd 1 Openssh 2025-04-03 10.0 HIGH 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-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-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-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-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-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-2001-0361 2 Openbsd, Ssh 2 Openssh, Ssh 2025-04-03 4.0 MEDIUM 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-2000-0999 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-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-2001-0872 3 Openbsd, Redhat, Suse 3 Openssh, Linux, Suse Linux 2025-04-03 7.2 HIGH 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-2000-0143 2 Openbsd, Ssh 2 Openssh, Ssh 2025-04-03 4.6 MEDIUM 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.
