| CVE | Vendors | Products | Updated | CVSS v3.1 |
|---|---|---|---|---|
| CVE-2004-2069 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2026-04-16 | 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-2001-0572 | 3 Openbsd, Redhat, Ssh | 3 Openssh, Linux, Ssh | 2026-04-16 | 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-2003-0693 | 2 Openbsd, Redhat | 3 Openssh, Enterprise Linux, Linux | 2026-04-16 | 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-2000-0525 | 1 Openbsd | 1 Openssh | 2026-04-16 | 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-2005-2798 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2026-04-16 | 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-2006-0883 | 2 Freebsd, Openbsd | 2 Freebsd, Openssh | 2026-04-16 | 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-2004-2760 | 1 Openbsd | 1 Openssh | 2026-04-16 | 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 | 2026-04-16 | 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-2000-0143 | 2 Openbsd, Ssh | 2 Openssh, Ssh | 2026-04-16 | 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-1999-1010 | 1 Openbsd | 1 Openssh | 2026-04-16 | 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-2000-0992 | 2 Openbsd, Ssh | 2 Openssh, Ssh | 2026-04-16 | 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-2001-1029 | 2 Freebsd, Openbsd | 2 Freebsd, Openssh | 2026-04-16 | 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-2025-61984 | 1 Openbsd | 1 Openssh | 2026-04-15 | 3.6 Low |
| ssh in OpenSSH before 10.1 allows control characters in usernames that originate from certain possibly untrusted sources, potentially leading to code execution when a ProxyCommand is used. The untrusted sources are the command line and %-sequence expansion of a configuration file. (A configuration file that provides a complete literal username is not categorized as an untrusted source.) | ||||
| CVE-2025-61985 | 1 Openbsd | 1 Openssh | 2026-04-15 | 3.6 Low |
| ssh in OpenSSH before 10.1 allows the '\0' character in an ssh:// URI, potentially leading to code execution when a ProxyCommand is used. | ||||
| CVE-2026-35414 | 1 Openbsd | 1 Openssh | 2026-04-10 | 4.2 Medium |
| OpenSSH before 10.3 mishandles the authorized_keys principals option in uncommon scenarios involving a principals list in conjunction with a Certificate Authority that makes certain use of comma characters. | ||||
| CVE-2026-35386 | 1 Openbsd | 1 Openssh | 2026-04-07 | 3.6 Low |
| In OpenSSH before 10.3, command execution can occur via shell metacharacters in a username within a command line. This requires a scenario where the username on the command line is untrusted, and also requires a non-default configurations of % in ssh_config. | ||||
| CVE-2026-35387 | 1 Openbsd | 1 Openssh | 2026-04-07 | 3.1 Low |
| OpenSSH before 10.3 can use unintended ECDSA algorithms. Listing of any ECDSA algorithm in PubkeyAcceptedAlgorithms or HostbasedAcceptedAlgorithms is misinterpreted to mean all ECDSA algorithms. | ||||
| CVE-2026-35388 | 1 Openbsd | 1 Openssh | 2026-04-07 | 2.5 Low |
| OpenSSH before 10.3 omits connection multiplexing confirmation for proxy-mode multiplexing sessions. | ||||
| CVE-2026-35385 | 1 Openbsd | 1 Openssh | 2026-04-03 | 7.5 High |
| In OpenSSH before 10.3, a file downloaded by scp may be installed setuid or setgid, an outcome contrary to some users' expectations, if the download is performed as root with -O (legacy scp protocol) and without -p (preserve mode). | ||||
| CVE-2025-26466 | 4 Canonical, Debian, Openbsd and 1 more | 5 Ubuntu Linux, Debian Linux, Openssh and 2 more | 2026-02-10 | 5.9 Medium |
| A flaw was found in the OpenSSH package. For each ping packet the SSH server receives, a pong packet is allocated in a memory buffer and stored in a queue of packages. It is only freed when the server/client key exchange has finished. A malicious client may keep sending such packages, leading to an uncontrolled increase in memory consumption on the server side. Consequently, the server may become unavailable, resulting in a denial of service attack. | ||||
