|---|---|---|---|---|---|
| CVE-2003-0695 | 1 Openbsd | 1 Openssh | 2026-04-16 | 7.5 HIGH | 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-2001-1507 | 1 Openbsd | 1 Openssh | 2026-04-16 | 7.5 HIGH | 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-2004-2230 | 1 Openbsd | 1 Openbsd | 2026-04-16 | 2.1 LOW | N/A |
| Heap-based buffer overflow in isakmpd on OpenBSD 3.4 through 3.6 allows local users to cause a denial of service (panic) and corrupt memory via IPSEC credentials on a socket. | |||||
| CVE-2003-1562 | 1 Openbsd | 1 Openssh | 2026-04-16 | 7.6 HIGH | 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-2000-0962 | 1 Openbsd | 1 Openbsd | 2026-04-16 | 5.0 MEDIUM | N/A |
| The IPSEC implementation in OpenBSD 2.7 does not properly handle empty AH/ESP packets, which allows remote attackers to cause a denial of service. | |||||
| CVE-1999-0727 | 1 Openbsd | 1 Openbsd | 2026-04-16 | 5.0 MEDIUM | N/A |
| A kernel leak in the OpenBSD kernel allows IPsec packets to be sent unencrypted. | |||||
| CVE-2001-0247 | 5 Freebsd, Mit, Netbsd and 2 more | 5 Freebsd, Kerberos 5, Netbsd and 2 more | 2026-04-16 | 10.0 HIGH | N/A |
| Buffer overflows in BSD-based FTP servers allows remote attackers to execute arbitrary commands via a long pattern string containing a {} sequence, as seen in (1) g_opendir, (2) g_lstat, (3) g_stat, and (4) the glob0 buffer as used in the glob functions glob2 and glob3. | |||||
| CVE-2001-1382 | 1 Openbsd | 1 Openssh | 2026-04-16 | 5.0 MEDIUM | 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-2004-0175 | 1 Openbsd | 1 Openssh | 2026-04-16 | 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-2001-1029 | 2 Freebsd, Openbsd | 2 Freebsd, Openssh | 2026-04-16 | 2.1 LOW | 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-2026-35414 | 1 Openbsd | 1 Openssh | 2026-04-10 | N/A | 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-2025-26466 | 3 Canonical, Debian, Openbsd | 3 Ubuntu Linux, Debian Linux, Openssh | 2026-02-10 | N/A | 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-2023-51385 | 2 Debian, Openbsd | 2 Debian Linux, Openssh | 2025-12-18 | 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-2020-14145 | 2 Netapp, Openbsd | 10 Active Iq Unified Manager, Aff A700s, Aff A700s Firmware and 7 more | 2025-12-18 | 4.3 MEDIUM | 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 | 5.8 MEDIUM | 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 | 4.0 MEDIUM | 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 | 5.0 MEDIUM | 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 | 2.6 LOW | 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 | 24 Ubuntu Linux, Debian Linux, Aff Baseboard Management Controller and 21 more | 2025-12-17 | 5.0 MEDIUM | 5.3 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 | N/A | 7.0 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." | |||||
