| CVE | Vendors | Products | Updated | CVSS v3.1 |
|---|---|---|---|---|
| CVE-2008-3259 | 1 Openbsd | 1 Openssh | 2025-04-09 | N/A |
| OpenSSH before 5.1 sets the SO_REUSEADDR socket option when the X11UseLocalhost configuration setting is disabled, which allows local users on some platforms to hijack the X11 forwarding port via a bind to a single IP address, as demonstrated on the HP-UX platform. | ||||
| CVE-2007-2243 | 1 Openbsd | 1 Openssh | 2025-04-09 | N/A |
| OpenSSH 4.6 and earlier, when ChallengeResponseAuthentication is enabled, allows remote attackers to determine the existence of user accounts by attempting to authenticate via S/KEY, which displays a different response if the user account exists, a similar issue to CVE-2001-1483. | ||||
| CVE-2006-5229 | 2 Novell, Openbsd | 2 Suse Linux, Openssh | 2025-04-09 | N/A |
| OpenSSH portable 4.1 on SUSE Linux, and possibly other platforms and versions, and possibly under limited configurations, allows remote attackers to determine valid usernames via timing discrepancies in which responses take longer for valid usernames than invalid ones, as demonstrated by sshtime. NOTE: as of 20061014, it appears that this issue is dependent on the use of manually-set passwords that causes delays when processing /etc/shadow due to an increased number of rounds. | ||||
| CVE-2008-1657 | 1 Openbsd | 1 Openssh | 2025-04-09 | N/A |
| OpenSSH 4.4 up to versions before 4.9 allows remote authenticated users to bypass the sshd_config ForceCommand directive by modifying the .ssh/rc session file. | ||||
| CVE-2008-4109 | 2 Debian, Openbsd | 2 Linux, Openssh | 2025-04-09 | N/A |
| A certain Debian patch for OpenSSH before 4.3p2-9etch3 on etch; before 4.6p1-1 on sid and lenny; and on other distributions such as SUSE uses functions that are not async-signal-safe in the signal handler for login timeouts, which allows remote attackers to cause a denial of service (connection slot exhaustion) via multiple login attempts. NOTE: this issue exists because of an incorrect fix for CVE-2006-5051. | ||||
| CVE-2006-5051 | 4 Apple, Debian, Openbsd and 1 more | 5 Mac Os X, Mac Os X Server, Debian Linux and 2 more | 2025-04-09 | 8.1 High |
| Signal handler race condition in OpenSSH before 4.4 allows remote attackers to cause a denial of service (crash), and possibly execute arbitrary code if GSSAPI authentication is enabled, via unspecified vectors that lead to a double-free. | ||||
| CVE-2008-5161 | 3 Openbsd, Redhat, Ssh | 6 Openssh, Enterprise Linux, Tectia Client and 3 more | 2025-04-09 | N/A |
| Error handling in the SSH protocol in (1) SSH Tectia Client and Server and Connector 4.0 through 4.4.11, 5.0 through 5.2.4, and 5.3 through 5.3.8; Client and Server and ConnectSecure 6.0 through 6.0.4; Server for Linux on IBM System z 6.0.4; Server for IBM z/OS 5.5.1 and earlier, 6.0.0, and 6.0.1; and Client 4.0-J through 4.3.3-J and 4.0-K through 4.3.10-K; and (2) OpenSSH 4.7p1 and possibly other versions, when using a block cipher algorithm in Cipher Block Chaining (CBC) mode, makes it easier for remote attackers to recover certain plaintext data from an arbitrary block of ciphertext in an SSH session via unknown vectors. | ||||
| CVE-2007-4752 | 2 Openbsd, Redhat | 3 Openssh, Enterprise Linux, Rhel Eus | 2025-04-09 | N/A |
| ssh in OpenSSH before 4.7 does not properly handle when an untrusted cookie cannot be created and uses a trusted X11 cookie instead, which allows attackers to violate intended policy and gain privileges by causing an X client to be treated as trusted. | ||||
| CVE-2001-0361 | 2 Openbsd, Ssh | 2 Openssh, Ssh | 2025-04-03 | 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-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-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-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-2003-0695 | 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-2003-1562 | 1 Openbsd | 1 Openssh | 2025-04-03 | 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-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-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-2000-0992 | 2 Openbsd, Ssh | 2 Openssh, Ssh | 2025-04-03 | 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-2002-0639 | 1 Openbsd | 1 Openssh | 2025-04-03 | 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. | ||||
