|---|---|---|---|---|---|
| CVE-2017-5850 | 1 Openbsd | 1 Openbsd | 2025-04-20 | 7.8 HIGH | 7.5 HIGH |
| httpd in OpenBSD allows remote attackers to cause a denial of service (memory consumption) via a series of requests for a large file using an HTTP Range header. | |||||
| CVE-2025-26465 | 4 Debian, Netapp, Openbsd and 1 more | 6 Debian Linux, Active Iq Unified Manager, Ontap and 3 more | 2025-04-14 | N/A | 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-2015-6565 | 1 Openbsd | 1 Openssh | 2025-04-12 | 7.2 HIGH | 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-2016-10009 | 1 Openbsd | 1 Openssh | 2025-04-12 | 7.5 HIGH | 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-2014-9278 | 2 Openbsd, Redhat | 3 Openssh, Enterprise Linux, Fedora | 2025-04-12 | 4.0 MEDIUM | 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-2016-8858 | 1 Openbsd | 1 Openssh | 2025-04-12 | 7.8 HIGH | 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-2015-8325 | 3 Canonical, Debian, Openbsd | 5 Ubuntu Core, Ubuntu Linux, Ubuntu Touch and 2 more | 2025-04-12 | 7.2 HIGH | 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-2016-6515 | 2 Fedoraproject, Openbsd | 2 Fedora, Openssh | 2025-04-12 | 7.8 HIGH | 7.5 HIGH |
| 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-2014-2532 | 2 Openbsd, Oracle | 2 Openssh, Communications User Data Repository | 2025-04-12 | 5.8 MEDIUM | 4.9 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-2013-2125 | 1 Openbsd | 1 Opensmtpd | 2025-04-12 | 5.0 MEDIUM | N/A |
| OpenSMTPD before 5.3.2 does not properly handle SSL sessions, which allows remote attackers to cause a denial of service (connection blocking) by keeping a connection open. | |||||
| CVE-2015-5600 | 1 Openbsd | 1 Openssh | 2025-04-12 | 8.5 HIGH | N/A |
| 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-2016-1907 | 1 Openbsd | 1 Openssh | 2025-04-12 | 5.0 MEDIUM | 5.3 MEDIUM |
| 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-2016-10010 | 1 Openbsd | 1 Openssh | 2025-04-12 | 6.9 MEDIUM | 7.0 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-2015-6564 | 1 Openbsd | 1 Openssh | 2025-04-12 | 6.9 MEDIUM | N/A |
| 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 | 2 Apple, Openbsd | 2 Mac Os X, Openssh | 2025-04-12 | 1.9 LOW | N/A |
| 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-2016-3115 | 2 Openbsd, Oracle | 2 Openssh, Vm Server | 2025-04-12 | 5.5 MEDIUM | 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-2016-10012 | 1 Openbsd | 1 Openssh | 2025-04-12 | 7.2 HIGH | 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-2015-5352 | 1 Openbsd | 1 Openssh | 2025-04-12 | 4.3 MEDIUM | 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-2016-0777 | 5 Apple, Hp, Openbsd and 2 more | 7 Mac Os X, Remote Device Access Virtual Customer Access System, Openssh and 4 more | 2025-04-12 | 4.0 MEDIUM | 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-2014-2653 | 1 Openbsd | 1 Openssh | 2025-04-12 | 5.8 MEDIUM | N/A |
| 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. | |||||
