|---|---|---|---|---|
| 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.' | ||||
| CVE-2018-20685 | 9 Canonical, Debian, Fujitsu and 6 more | 30 Ubuntu Linux, Debian Linux, M10-1 and 27 more | 2025-12-17 | 5.3 Medium |
| In OpenSSH 7.9, scp.c in the scp client allows remote SSH servers to bypass intended access restrictions via the filename of . or an empty filename. The impact is modifying the permissions of the target directory on the client side. | ||||
| CVE-2018-15473 | 7 Canonical, Debian, Netapp and 4 more | 25 Ubuntu Linux, Debian Linux, Aff Baseboard Management Controller and 22 more | 2025-12-17 | 5.9 Medium |
| OpenSSH through 7.7 is prone to a user enumeration vulnerability due to not delaying bailout for an invalid authenticating user until after the packet containing the request has been fully parsed, related to auth2-gss.c, auth2-hostbased.c, and auth2-pubkey.c. | ||||
| CVE-2023-51767 | 3 Fedoraproject, Openbsd, Redhat | 3 Fedora, Openssh, Enterprise Linux | 2025-11-18 | 7 High |
| OpenSSH through 10.0, 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. NOTE: this is disputed by the Supplier, who states "we do not consider it to be the application's responsibility to defend against platform architectural weaknesses." | ||||
| CVE-2020-15778 | 4 Broadcom, Netapp, Openbsd and 1 more | 11 Fabric Operating System, A700s, A700s Firmware and 8 more | 2025-07-28 | 7.8 High |
| scp in OpenSSH through 8.3p1 allows command injection in the scp.c toremote function, as demonstrated by backtick characters in the destination argument. NOTE: the vendor reportedly has stated that they intentionally omit validation of "anomalous argument transfers" because that could "stand a great chance of breaking existing workflows." | ||||
| CVE-2025-32728 | 2 Debian, Openbsd | 2 Debian Linux, Openssh | 2025-05-22 | 4.3 Medium |
| In sshd in OpenSSH before 10.0, the DisableForwarding directive does not adhere to the documentation stating that it disables X11 and agent forwarding. | ||||
| CVE-2019-16905 | 3 Netapp, Openbsd, Siemens | 7 Cloud Backup, Steelstore Cloud Integrated Storage, Openssh and 4 more | 2025-04-23 | 7.8 High |
| OpenSSH 7.7 through 7.9 and 8.x before 8.1, when compiled with an experimental key type, has a pre-authentication integer overflow if a client or server is configured to use a crafted XMSS key. This leads to memory corruption and local code execution because of an error in the XMSS key parsing algorithm. NOTE: the XMSS implementation is considered experimental in all released OpenSSH versions, and there is no supported way to enable it when building portable OpenSSH. | ||||
| CVE-2017-15906 | 5 Debian, Netapp, Openbsd and 2 more | 23 Debian Linux, Active Iq Unified Manager, Cloud Backup and 20 more | 2025-04-20 | 5.3 Medium |
| The process_open function in sftp-server.c in OpenSSH before 7.6 does not properly prevent write operations in readonly mode, which allows attackers to create zero-length files. | ||||
| CVE-2015-5352 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-12 | N/A |
| The x11_open_helper function in channels.c in ssh in OpenSSH before 6.9, when ForwardX11Trusted mode is not used, lacks a check of the refusal deadline for X connections, which makes it easier for remote attackers to bypass intended access restrictions via a connection outside of the permitted time window. | ||||
| CVE-2016-1907 | 1 Openbsd | 1 Openssh | 2025-04-12 | N/A |
| The ssh_packet_read_poll2 function in packet.c in OpenSSH before 7.1p2 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via crafted network traffic. | ||||
| CVE-2014-9278 | 2 Openbsd, Redhat | 3 Openssh, Enterprise Linux, Fedora | 2025-04-12 | N/A |
| The OpenSSH server, as used in Fedora and Red Hat Enterprise Linux 7 and when running in a Kerberos environment, allows remote authenticated users to log in as another user when they are listed in the .k5users file of that user, which might bypass intended authentication requirements that would force a local login. | ||||
| CVE-2016-6515 | 3 Fedoraproject, Openbsd, Redhat | 3 Fedora, Openssh, Enterprise Linux | 2025-04-12 | N/A |
| The auth_password function in auth-passwd.c in sshd in OpenSSH before 7.3 does not limit password lengths for password authentication, which allows remote attackers to cause a denial of service (crypt CPU consumption) via a long string. | ||||
| CVE-2015-6565 | 1 Openbsd | 1 Openssh | 2025-04-12 | N/A |
| sshd in OpenSSH 6.8 and 6.9 uses world-writable permissions for TTY devices, which allows local users to cause a denial of service (terminal disruption) or possibly have unspecified other impact by writing to a device, as demonstrated by writing an escape sequence. | ||||
| CVE-2010-4755 | 3 Freebsd, Netbsd, Openbsd | 4 Freebsd, Netbsd, Openbsd and 1 more | 2025-04-11 | N/A |
| The (1) remote_glob function in sftp-glob.c and the (2) process_put function in sftp.c in OpenSSH 5.8 and earlier, as used in FreeBSD 7.3 and 8.1, NetBSD 5.0.2, OpenBSD 4.7, and other products, allow remote authenticated users to cause a denial of service (CPU and memory consumption) via crafted glob expressions that do not match any pathnames, as demonstrated by glob expressions in SSH_FXP_STAT requests to an sftp daemon, a different vulnerability than CVE-2010-2632. | ||||
| CVE-2013-4548 | 1 Openbsd | 1 Openssh | 2025-04-11 | N/A |
| The mm_newkeys_from_blob function in monitor_wrap.c in sshd in OpenSSH 6.2 and 6.3, when an AES-GCM cipher is used, does not properly initialize memory for a MAC context data structure, which allows remote authenticated users to bypass intended ForceCommand and login-shell restrictions via packet data that provides a crafted callback address. | ||||
| CVE-2011-5000 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-11 | N/A |
| The ssh_gssapi_parse_ename function in gss-serv.c in OpenSSH 5.8 and earlier, when gssapi-with-mic authentication is enabled, allows remote authenticated users to cause a denial of service (memory consumption) via a large value in a certain length field. NOTE: there may be limited scenarios in which this issue is relevant. | ||||
| CVE-2023-38408 | 3 Fedoraproject, Openbsd, Redhat | 9 Fedora, Openssh, Devworkspace and 6 more | 2024-11-21 | 9.8 Critical |
| The PKCS#11 feature in ssh-agent in OpenSSH before 9.3p2 has an insufficiently trustworthy search path, leading to remote code execution if an agent is forwarded to an attacker-controlled system. (Code in /usr/lib is not necessarily safe for loading into ssh-agent.) NOTE: this issue exists because of an incomplete fix for CVE-2016-10009. | ||||
