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-2001-1585 | 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-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-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-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-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-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. | |||||
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-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-1999-1010 | 1 Openbsd | 1 Openssh | 2025-04-03 | 2.1 LOW | 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-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-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-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-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-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-2023-51767 | 3 Fedoraproject, Openbsd, Redhat | 3 Fedora, Openssh, Enterprise Linux | 2024-11-21 | N/A | 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 | 2 Debian, Openbsd | 2 Debian Linux, Openssh | 2024-11-21 | N/A | 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. | |||||
CVE-2023-51384 | 2 Debian, Openbsd | 2 Debian Linux, Openssh | 2024-11-21 | N/A | 5.5 MEDIUM |
In ssh-agent in OpenSSH before 9.6, certain destination constraints can be incompletely applied. When destination constraints are specified during addition of PKCS#11-hosted private keys, these constraints are only applied to the first key, even if a PKCS#11 token returns multiple keys. | |||||
CVE-2023-38408 | 2 Fedoraproject, Openbsd | 2 Fedora, Openssh | 2024-11-21 | N/A | 9.8 CRITICAL |
The PKCS#11 feature in ssh-agent in OpenSSH before 9.3p2 has an insufficiently trustworthy search path, leading to remote code execution if an agent is forwarded to an attacker-controlled system. (Code in /usr/lib is not necessarily safe for loading into ssh-agent.) NOTE: this issue exists because of an incomplete fix for CVE-2016-10009. |
