CVE-2003-0386 2 Openbsd, Redhat 2 Openssh, Enterprise Linux 2026-04-16 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-2003-0787 1 Openbsd 1 Openssh 2026-04-16 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-2004-0175 2 Openbsd, Redhat 2 Openssh, Enterprise Linux 2026-04-16 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-2001-0872 3 Openbsd, Redhat, Suse 3 Openssh, Linux, Suse Linux 2026-04-16 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-2000-0999 1 Openbsd 1 Openssh 2026-04-16 N/A
Format string vulnerabilities in OpenBSD ssh program (and possibly other BSD-based operating systems) allow attackers to gain root privileges.
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-2001-1507 1 Openbsd 1 Openssh 2026-04-16 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-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-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.
CVE-2020-14145 3 Netapp, Openbsd, Redhat 11 Active Iq Unified Manager, Aff A700s, Aff A700s Firmware and 8 more 2025-12-18 5.9 Medium
The client side in OpenSSH 5.7 through 8.4 has an Observable Discrepancy leading to an information leak in the algorithm negotiation. This allows man-in-the-middle attackers to target initial connection attempts (where no host key for the server has been cached by the client). NOTE: some reports state that 8.5 and 8.6 are also affected.
CVE-2019-6111 10 Apache, Canonical, Debian and 7 more 27 Mina Sshd, Ubuntu Linux, Debian Linux and 24 more 2025-12-18 5.9 Medium
An issue was discovered in OpenSSH 7.9. Due to the scp implementation being derived from 1983 rcp, the server chooses which files/directories are sent to the client. However, the scp client only performs cursory validation of the object name returned (only directory traversal attacks are prevented). A malicious scp server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the scp client target directory. If recursive operation (-r) is performed, the server can manipulate subdirectories as well (for example, to overwrite the .ssh/authorized_keys file).
CVE-2019-6110 4 Netapp, Openbsd, Siemens and 1 more 9 Element Software, Ontap Select Deploy, Storage Automation Store and 6 more 2025-12-18 6.8 Medium
In OpenSSH 7.9, due to accepting and displaying arbitrary stderr output from the server, a malicious server (or Man-in-The-Middle attacker) can manipulate the client output, for example to use ANSI control codes to hide additional files being transferred.
CVE-2018-15919 2 Netapp, Openbsd 7 Cloud Backup, Cn1610, Cn1610 Firmware and 4 more 2025-12-18 5.3 Medium
Remotely observable behaviour in auth-gss2.c in OpenSSH through 7.8 could be used by remote attackers to detect existence of users on a target system when GSS2 is in use. NOTE: the discoverer states 'We understand that the OpenSSH developers do not want to treat such a username enumeration (or "oracle") as a vulnerability.'
