| CVE-2026-3497 | 5 Canonical, Debian, Openbsd and 2 more | 5 Ubuntu Linux, Debian Linux, Openssh and 2 more | 2026-06-02 | 7.5 High |
| Vulnerability in the OpenSSH GSSAPI delta included in various Linux distributions. This vulnerability affects the GSSAPI patches added by various Linux distributions and does not affect the OpenSSH upstream project itself. The usage of sshpkt_disconnect() on an error, which does not terminate the process, allows an attacker to send an unexpected GSSAPI message type during the GSSAPI key exchange to the server, which will call the underlying function and continue the execution of the program without setting the related connection variables. As the variables are not initialized to NULL the code later accesses those uninitialized variables, accessing random memory, which could lead to undefined behavior. The recommended workaround is to use ssh_packet_disconnect() instead, which does terminate the process. The impact of the vulnerability depends heavily on the compiler flag hardening configuration. | ||||
| CVE-2016-8858 | 1 Openbsd | 1 Openssh | 2026-05-29 | 7.5 High |
| The kex_input_kexinit function in kex.c in OpenSSH 6.x and 7.x through 7.3 allows remote attackers to cause a denial of service (memory consumption) by sending many duplicate KEXINIT requests. NOTE: a third party reports that "OpenSSH upstream does not consider this as a security issue." | ||||
| CVE-2016-6210 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2026-05-29 | 5.9 Medium |
| sshd in OpenSSH before 7.3, when SHA256 or SHA512 are used for user password hashing, uses BLOWFISH hashing on a static password when the username does not exist, which allows remote attackers to enumerate users by leveraging the timing difference between responses when a large password is provided. | ||||
| CVE-2016-3115 | 3 Openbsd, Oracle, Redhat | 3 Openssh, Vm Server, Enterprise Linux | 2026-05-29 | 6.4 Medium |
| Multiple CRLF injection vulnerabilities in session.c in sshd in OpenSSH before 7.2p2 allow remote authenticated users to bypass intended shell-command restrictions via crafted X11 forwarding data, related to the (1) do_authenticated1 and (2) session_x11_req functions. | ||||
| CVE-2016-1908 | 4 Debian, Openbsd, Oracle and 1 more | 10 Debian Linux, Openssh, Linux and 7 more | 2026-05-29 | 9.8 Critical |
| The client in OpenSSH before 7.2 mishandles failed cookie generation for untrusted X11 forwarding and relies on the local X11 server for access-control decisions, which allows remote X11 clients to trigger a fallback and obtain trusted X11 forwarding privileges by leveraging configuration issues on this X11 server, as demonstrated by lack of the SECURITY extension on this X11 server. | ||||
| CVE-2016-10012 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2026-05-29 | 7.8 High |
| The shared memory manager (associated with pre-authentication compression) in sshd in OpenSSH before 7.4 does not ensure that a bounds check is enforced by all compilers, which might allows local users to gain privileges by leveraging access to a sandboxed privilege-separation process, related to the m_zback and m_zlib data structures. | ||||
| CVE-2016-10011 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2026-05-29 | 6.2 Medium |
| authfile.c in sshd in OpenSSH before 7.4 does not properly consider the effects of realloc on buffer contents, which might allow local users to obtain sensitive private-key information by leveraging access to a privilege-separated child process. | ||||
| CVE-2016-10010 | 1 Openbsd | 1 Openssh | 2026-05-29 | 7 High |
| sshd in OpenSSH before 7.4, when privilege separation is not used, creates forwarded Unix-domain sockets as root, which might allow local users to gain privileges via unspecified vectors, related to serverloop.c. | ||||
| CVE-2016-10009 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2026-05-29 | 7.3 High |
| Untrusted search path vulnerability in ssh-agent.c in ssh-agent in OpenSSH before 7.4 allows remote attackers to execute arbitrary local PKCS#11 modules by leveraging control over a forwarded agent-socket. | ||||
| CVE-2016-0778 | 6 Apple, Hp, Openbsd and 3 more | 7 Mac Os X, Virtual Customer Access System, Openssh and 4 more | 2026-05-29 | 8.1 High |
| The (1) roaming_read and (2) roaming_write functions in roaming_common.c in the client in OpenSSH 5.x, 6.x, and 7.x before 7.1p2, when certain proxy and forward options are enabled, do not properly maintain connection file descriptors, which allows remote servers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact by requesting many forwardings. | ||||
| CVE-2016-0777 | 6 Apple, Hp, Openbsd and 3 more | 8 Mac Os X, Remote Device Access Virtual Customer Access System, Openssh and 5 more | 2026-05-29 | 6.5 Medium |
| The resend_bytes function in roaming_common.c in the client in OpenSSH 5.x, 6.x, and 7.x before 7.1p2 allows remote servers to obtain sensitive information from process memory by requesting transmission of an entire buffer, as demonstrated by reading a private key. | ||||
| CVE-2011-4327 | 1 Openbsd | 1 Openssh | 2026-05-29 | 5.5 Medium |
| ssh-keysign.c in ssh-keysign in OpenSSH before 5.8p2 on certain platforms executes ssh-rand-helper with unintended open file descriptors, which allows local users to obtain sensitive key information via the ptrace system call. | ||||
| CVE-2011-0539 | 1 Openbsd | 1 Openssh | 2026-05-29 | 7.5 High |
| The key_certify function in usr.bin/ssh/key.c in OpenSSH 5.6 and 5.7, when generating legacy certificates using the -t command-line option in ssh-keygen, does not initialize the nonce field, which might allow remote attackers to obtain sensitive stack memory contents or make it easier to conduct hash collision attacks. | ||||
| CVE-2010-5107 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2026-05-29 | 7.5 High |
| The default configuration of OpenSSH through 6.1 enforces a fixed time limit between establishing a TCP connection and completing a login, which makes it easier for remote attackers to cause a denial of service (connection-slot exhaustion) by periodically making many new TCP connections. | ||||
| CVE-2016-20012 | 2 Netapp, Openbsd | 5 Clustered Data Ontap, Hci Management Node, Ontap Select Deploy Administration Utility and 2 more | 2026-05-29 | 5.3 Medium |
| OpenSSH through 8.7 allows remote attackers, who have a suspicion that a certain combination of username and public key is known to an SSH server, to test whether this suspicion is correct. This occurs because a challenge is sent only when that combination could be valid for a login session. NOTE: the vendor does not recognize user enumeration as a vulnerability for this product | ||||
| CVE-2010-4478 | 1 Openbsd | 1 Openssh | 2026-05-28 | 9.8 Critical |
| OpenSSH 5.6 and earlier, when J-PAKE is enabled, does not properly validate the public parameters in the J-PAKE protocol, which allows remote attackers to bypass the need for knowledge of the shared secret, and successfully authenticate, by sending crafted values in each round of the protocol, a related issue to CVE-2010-4252. | ||||
| CVE-2023-28531 | 2 Netapp, Openbsd | 4 Brocade Fabric Operating System, Hci Bootstrap Os, Solidfire Element Os and 1 more | 2026-05-28 | 9.8 Critical |
| ssh-add in OpenSSH before 9.3 adds smartcard keys to ssh-agent without the intended per-hop destination constraints. The earliest affected version is 8.9. | ||||
| CVE-2008-5161 | 3 Openbsd, Redhat, Ssh | 6 Openssh, Enterprise Linux, Tectia Client and 3 more | 2026-05-28 | 3.7 Low |
| Error handling in the SSH protocol in (1) SSH Tectia Client and Server and Connector 4.0 through 4.4.11, 5.0 through 5.2.4, and 5.3 through 5.3.8; Client and Server and ConnectSecure 6.0 through 6.0.4; Server for Linux on IBM System z 6.0.4; Server for IBM z/OS 5.5.1 and earlier, 6.0.0, and 6.0.1; and Client 4.0-J through 4.3.3-J and 4.0-K through 4.3.10-K; and (2) OpenSSH 4.7p1 and possibly other versions, when using a block cipher algorithm in Cipher Block Chaining (CBC) mode, makes it easier for remote attackers to recover certain plaintext data from an arbitrary block of ciphertext in an SSH session via unknown vectors. | ||||
| CVE-2023-51384 | 2 Debian, Openbsd | 2 Debian Linux, Openssh | 2026-05-28 | 5.5 Medium |
| In ssh-agent in OpenSSH before 9.6, certain destination constraints can be incompletely applied. When destination constraints are specified during addition of PKCS#11-hosted private keys, these constraints are only applied to the first key, even if a PKCS#11 token returns multiple keys. | ||||
| CVE-2014-2653 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2026-05-28 | 6.5 Medium |
| The verify_host_key function in sshconnect.c in the client in OpenSSH 6.6 and earlier allows remote servers to trigger the skipping of SSHFP DNS RR checking by presenting an unacceptable HostCertificate. | ||||
