|---|---|---|---|---|
| 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-2025-62875 | 4 Openbsd, Opensmtpd, Opensuse and 1 more | 5 Opensmtpd, Opensmtpd, Tumbleweed and 2 more | 2026-01-15 | 5.5 Medium |
| An Improper Check for Unusual or Exceptional Conditions vulnerability in OpenSMTPD allows local users to crash OpenSMTPD. This issue affects openSUSE Tumbleweed: from ? before 7.8.0p0-1.1. | ||||
| 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-2020-7247 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2025-11-07 | 9.8 Critical |
| smtp_mailaddr in smtp_session.c in OpenSMTPD 6.6, as used in OpenBSD 6.6 and other products, allows remote attackers to execute arbitrary commands as root via a crafted SMTP session, as demonstrated by shell metacharacters in a MAIL FROM field. This affects the "uncommented" default configuration. The issue exists because of an incorrect return value upon failure of input validation. | ||||
| CVE-2023-29323 | 2 Openbsd, Opensmtpd | 2 Openbsd, Opensmtpd | 2025-11-04 | 7.8 High |
| ascii_load_sockaddr in smtpd in OpenBSD before 7.1 errata 024 and 7.2 before errata 020, and OpenSMTPD Portable before 7.0.0-portable commit f748277, can abort upon a connection from a local, scoped IPv6 address. | ||||
| CVE-2023-52557 | 1 Openbsd | 1 Openbsd | 2025-10-10 | 7.5 High |
| In OpenBSD 7.3 before errata 016, npppd(8) could crash by a l2tp message which has an AVP (Attribute-Value Pair) with wrong length. | ||||
| CVE-2023-52556 | 1 Openbsd | 1 Openbsd | 2025-10-10 | 6.2 Medium |
| In OpenBSD 7.4 before errata 009, a race condition between pf(4)'s processing of packets and expiration of packet states may cause a kernel panic. | ||||
| CVE-2023-52558 | 1 Openbsd | 1 Openbsd | 2025-10-10 | 7.5 High |
| In OpenBSD 7.4 before errata 002 and OpenBSD 7.3 before errata 019, a network buffer that had to be split at certain length that could crash the kernel after receiving specially crafted escape sequences. | ||||
| CVE-2024-10934 | 1 Openbsd | 1 Openbsd | 2025-10-02 | 9.8 Critical |
| In OpenBSD 7.5 before errata 008 and OpenBSD 7.4 before errata 021, avoid possible mbuf double free in NFS client and server implementation, do not use uninitialized variable in error handling of NFS server. | ||||
| CVE-2024-10933 | 1 Openbsd | 1 Openbsd | 2025-09-23 | 5 Medium |
| In OpenBSD 7.5 before errata 009 and OpenBSD 7.4 before errata 022, exclude any '/' in readdir name validation to avoid unexpected directory traversal on untrusted file systems. | ||||
| CVE-2024-11148 | 1 Openbsd | 1 Openbsd | 2025-09-23 | 7.5 High |
| In OpenBSD 7.4 before errata 006 and OpenBSD 7.3 before errata 020, httpd(8) is vulnerable to a NULL dereference when handling a malformed fastcgi request. | ||||
