| CVE | Vendors | Products | Updated | CVSS v3.1 |
|---|---|---|---|---|
| CVE-2003-0190 | 4 Openbsd, Openpkg, Redhat and 1 more | 8 Openssh, Openpkg, Enterprise Linux and 5 more | 2025-04-03 | 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 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-03 | 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-2003-0693 | 2 Openbsd, Redhat | 3 Openssh, Enterprise Linux, Linux | 2025-04-03 | 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-2003-0786 | 1 Openbsd | 1 Openssh | 2025-04-03 | 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-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-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-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-2000-0999 | 1 Openbsd | 1 Openssh | 2025-04-03 | N/A |
| Format string vulnerabilities in OpenBSD ssh program (and possibly other BSD-based operating systems) allow attackers to gain root privileges. | ||||
| 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-2001-0572 | 3 Openbsd, Redhat, Ssh | 3 Openssh, Linux, Ssh | 2025-04-03 | N/A |
| The SSH protocols 1 and 2 (aka SSH-2) as implemented in OpenSSH and other packages have various weaknesses which can allow a remote attacker to obtain the following information via sniffing: (1) password lengths or ranges of lengths, which simplifies brute force password guessing, (2) whether RSA or DSA authentication is being used, (3) the number of authorized_keys in RSA authentication, or (4) the lengths of shell commands. | ||||
| 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-2003-0682 | 2 Openbsd, Redhat | 3 Openssh, Enterprise Linux, Linux | 2025-04-03 | 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-2003-0695 | 2 Openbsd, Redhat | 3 Openssh, Enterprise Linux, Linux | 2025-04-03 | 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-2003-0787 | 1 Openbsd | 1 Openssh | 2025-04-03 | N/A |
| The PAM conversation function in OpenSSH 3.7.1 and 3.7.1p1 interprets an array of structures as an array of pointers, which allows attackers to modify the stack and possibly gain 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-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-2005-2666 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-03 | 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-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-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. | ||||
