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-2000-0217 2 Openbsd, Ssh 3 Openssh, Ssh, Ssh2 2025-04-03 5.1 MEDIUM N/A
The default configuration of SSH allows X forwarding, which could allow a remote attacker to control a client's X sessions via a malicious xauth program.
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-2001-0572 2 Openbsd, Ssh 2 Openssh, Ssh 2025-04-03 7.5 HIGH 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-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-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-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-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-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-2004-2069 1 Openbsd 1 Openssh 2025-04-03 5.0 MEDIUM 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-2000-1169 1 Openbsd 1 Openssh 2025-04-03 7.5 HIGH 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-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-2001-0529 1 Openbsd 1 Openssh 2025-04-03 7.2 HIGH N/A
OpenSSH version 2.9 and earlier, with X forwarding enabled, allows a local attacker to delete any file named 'cookies' via a symlink attack.
CVE-2003-0787 1 Openbsd 1 Openssh 2025-04-03 7.5 HIGH 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-2005-2798 1 Openbsd 1 Openssh 2025-04-03 5.0 MEDIUM 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-2004-0175 1 Openbsd 1 Openssh 2025-04-03 4.3 MEDIUM 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-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-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.
