|---|---|---|---|---|
| CVE-2014-2532 | 3 Openbsd, Oracle, Redhat | 3 Openssh, Communications User Data Repository, Enterprise Linux | 2026-05-28 | 4.2 Medium |
| sshd in OpenSSH before 6.6 does not properly support wildcards on AcceptEnv lines in sshd_config, which allows remote attackers to bypass intended environment restrictions by using a substring located before a wildcard character. | ||||
| CVE-2014-1692 | 1 Openbsd | 1 Openssh | 2026-05-28 | 7.3 High |
| The hash_buffer function in schnorr.c in OpenSSH through 6.4, when Makefile.inc is modified to enable the J-PAKE protocol, does not initialize certain data structures, which might allow remote attackers to cause a denial of service (memory corruption) or have unspecified other impact via vectors that trigger an error condition. | ||||
| CVE-2015-6564 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2026-05-27 | 7 High |
| Use-after-free vulnerability in the mm_answer_pam_free_ctx function in monitor.c in sshd in OpenSSH before 7.0 on non-OpenBSD platforms might allow local users to gain privileges by leveraging control of the sshd uid to send an unexpectedly early MONITOR_REQ_PAM_FREE_CTX request. | ||||
| CVE-2015-6563 | 3 Apple, Openbsd, Redhat | 3 Mac Os X, Openssh, Enterprise Linux | 2026-05-27 | 6.4 Medium |
| The monitor component in sshd in OpenSSH before 7.0 on non-OpenBSD platforms accepts extraneous username data in MONITOR_REQ_PAM_INIT_CTX requests, which allows local users to conduct impersonation attacks by leveraging any SSH login access in conjunction with control of the sshd uid to send a crafted MONITOR_REQ_PWNAM request, related to monitor.c and monitor_wrap.c. | ||||
| CVE-2015-5600 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2026-05-27 | 8.1 High |
| The kbdint_next_device function in auth2-chall.c in sshd in OpenSSH through 6.9 does not properly restrict the processing of keyboard-interactive devices within a single connection, which makes it easier for remote attackers to conduct brute-force attacks or cause a denial of service (CPU consumption) via a long and duplicative list in the ssh -oKbdInteractiveDevices option, as demonstrated by a modified client that provides a different password for each pam element on this list. | ||||
| CVE-2015-8325 | 4 Canonical, Debian, Openbsd and 1 more | 6 Ubuntu Core, Ubuntu Linux, Ubuntu Touch and 3 more | 2026-05-22 | 7.8 High |
| The do_setup_env function in session.c in sshd in OpenSSH through 7.2p2, when the UseLogin feature is enabled and PAM is configured to read .pam_environment files in user home directories, allows local users to gain privileges by triggering a crafted environment for the /bin/login program, as demonstrated by an LD_PRELOAD environment variable. | ||||
| CVE-2012-0814 | 1 Openbsd | 1 Openssh | 2026-05-22 | 6.5 Medium |
| The auth_parse_options function in auth-options.c in sshd in OpenSSH before 5.7 provides debug messages containing authorized_keys command options, which allows remote authenticated users to obtain potentially sensitive information by reading these messages, as demonstrated by the shared user account required by Gitolite. NOTE: this can cross privilege boundaries because a user account may intentionally have no shell or filesystem access, and therefore may have no supported way to read an authorized_keys file in its own home directory. | ||||
| CVE-2025-26465 | 4 Debian, Netapp, Openbsd and 1 more | 9 Debian Linux, Active Iq Unified Manager, Ontap and 6 more | 2026-05-12 | 6.8 Medium |
| A vulnerability was found in OpenSSH when the VerifyHostKeyDNS option is enabled. A machine-in-the-middle attack can be performed by a malicious machine impersonating a legit server. This issue occurs due to how OpenSSH mishandles error codes in specific conditions when verifying the host key. For an attack to be considered successful, the attacker needs to manage to exhaust the client's memory resource first, turning the attack complexity high. | ||||
| CVE-2024-6387 | 13 Almalinux, Amazon, Apple and 10 more | 85 Almalinux, Amazon Linux, Macos and 82 more | 2026-05-12 | 8.1 High |
| A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd). There is a race condition which can lead sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a set time period. | ||||
| CVE-2023-51385 | 3 Debian, Openbsd, Redhat | 5 Debian Linux, Openssh, Enterprise Linux and 2 more | 2026-05-12 | 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-2023-48795 | 42 9bis, Apache, Apple and 39 more | 77 Kitty, Sshd, Sshj and 74 more | 2026-05-12 | 5.9 Medium |
| The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms.

| sshd in OpenSSH 6.2 through 8.x before 8.8, when certain non-default configurations are used, allows privilege escalation because supplemental groups are not initialized as expected. Helper programs for AuthorizedKeysCommand and AuthorizedPrincipalsCommand may run with privileges associated with group memberships of the sshd process, if the configuration specifies running the command as a different user. | ||||
| CVE-2026-41285 | 1 Openbsd | 1 Openbsd | 2026-04-28 | 4.3 Medium |
| In OpenBSD through 7.8, the slaacd and rad daemons have an infinite loop when they receive a crafted ICMPv6 Neighbor Discovery (ND) option (over a local network) with length zero, because of an "nd_opt_len * 8 - 2" expression with no preceding check for whether nd_opt_len is zero. | ||||
| CVE-2016-10708 | 5 Canonical, Debian, Netapp and 2 more | 13 Ubuntu Linux, Debian Linux, Cloud Backup and 10 more | 2026-04-28 | 7.5 High |
| sshd in OpenSSH before 7.4 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an out-of-sequence NEWKEYS message, as demonstrated by Honggfuzz, related to kex.c and packet.c. | ||||
| CVE-2007-4305 | 5 Netbsd, Openbsd, Sysjail and 2 more | 5 Netbsd, Openbsd, Sysjail and 2 more | 2026-04-23 | N/A |
| Multiple race conditions in the (1) Sudo monitor mode and (2) Sysjail policies in Systrace on NetBSD and OpenBSD allow local users to defeat system call interposition, and consequently bypass access control policy and auditing. | ||||
| CVE-2007-1365 | 1 Openbsd | 1 Openbsd | 2026-04-23 | N/A |
| Buffer overflow in kern/uipc_mbuf2.c in OpenBSD 3.9 and 4.0 allows remote attackers to execute arbitrary code via fragmented IPv6 packets due to "incorrect mbuf handling for ICMP6 packets." NOTE: this was originally reported as a denial of service. | ||||
| CVE-2007-3102 | 3 Fedora Project, Openbsd, Redhat | 3 Fedora Core, Openssh, Enterprise Linux | 2026-04-23 | N/A |
| Unspecified vulnerability in the linux_audit_record_event function in OpenSSH 4.3p2, as used on Fedora Core 6 and possibly other systems, allows remote attackers to write arbitrary characters to an audit log via a crafted username. NOTE: some of these details are obtained from third party information. | ||||
| CVE-2007-1352 | 8 Mandrakesoft, Openbsd, Redhat and 5 more | 14 Mandrake Linux, Mandrake Linux Corporate Server, Mandrake Multi Network Firewall and 11 more | 2026-04-23 | N/A |
| Integer overflow in the FontFileInitTable function in X.Org libXfont before 20070403 allows remote authenticated users to execute arbitrary code via a long first line in the fonts.dir file, which results in a heap overflow. | ||||
| CVE-2008-3234 | 2 Debian, Openbsd | 2 Debian Linux, Openssh | 2026-04-23 | N/A |
| sshd in OpenSSH 4 on Debian GNU/Linux, and the 20070303 OpenSSH snapshot, allows remote authenticated users to obtain access to arbitrary SELinux roles by appending a :/ (colon slash) sequence, followed by the role name, to the username. | ||||
| CVE-2009-2904 | 3 Fedoraproject, Openbsd, Redhat | 5 Fedora, Openssh, Enterprise Linux and 2 more | 2026-04-23 | N/A |
| A certain Red Hat modification to the ChrootDirectory feature in OpenSSH 4.8, as used in sshd in OpenSSH 4.3 in Red Hat Enterprise Linux (RHEL) 5.4 and Fedora 11, allows local users to gain privileges via hard links to setuid programs that use configuration files within the chroot directory, related to requirements for directory ownership. | ||||
