CVE-2016-8858 | 1 Openbsd | 1 Openssh | 2025-04-12 | N/A |
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-2015-6563 | 3 Apple, Openbsd, Redhat | 3 Mac Os X, Openssh, Enterprise Linux | 2025-04-12 | 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-2014-9278 | 2 Openbsd, Redhat | 3 Openssh, Enterprise Linux, Fedora | 2025-04-12 | 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-2014-2653 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-12 | 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. | ||||
CVE-2016-1907 | 1 Openbsd | 1 Openssh | 2025-04-12 | N/A |
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-2016-3115 | 3 Openbsd, Oracle, Redhat | 3 Openssh, Vm Server, Enterprise Linux | 2025-04-12 | N/A |
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-2015-5352 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-12 | 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-2015-6564 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-12 | 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-2016-10010 | 1 Openbsd | 1 Openssh | 2025-04-12 | N/A |
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-2010-4478 | 1 Openbsd | 1 Openssh | 2025-04-11 | N/A |
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-2010-5107 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-11 | N/A |
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-2010-4755 | 3 Freebsd, Netbsd, Openbsd | 4 Freebsd, Netbsd, Openbsd and 1 more | 2025-04-11 | N/A |
The (1) remote_glob function in sftp-glob.c and the (2) process_put function in sftp.c in OpenSSH 5.8 and earlier, as used in FreeBSD 7.3 and 8.1, NetBSD 5.0.2, OpenBSD 4.7, and other products, allow remote authenticated users to cause a denial of service (CPU and memory consumption) via crafted glob expressions that do not match any pathnames, as demonstrated by glob expressions in SSH_FXP_STAT requests to an sftp daemon, a different vulnerability than CVE-2010-2632. | ||||
CVE-2013-4548 | 1 Openbsd | 1 Openssh | 2025-04-11 | N/A |
The mm_newkeys_from_blob function in monitor_wrap.c in sshd in OpenSSH 6.2 and 6.3, when an AES-GCM cipher is used, does not properly initialize memory for a MAC context data structure, which allows remote authenticated users to bypass intended ForceCommand and login-shell restrictions via packet data that provides a crafted callback address. | ||||
CVE-2011-5000 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-11 | N/A |
The ssh_gssapi_parse_ename function in gss-serv.c in OpenSSH 5.8 and earlier, when gssapi-with-mic authentication is enabled, allows remote authenticated users to cause a denial of service (memory consumption) via a large value in a certain length field. NOTE: there may be limited scenarios in which this issue is relevant. | ||||
CVE-2011-4327 | 1 Openbsd | 1 Openssh | 2025-04-11 | N/A |
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-2012-0814 | 1 Openbsd | 1 Openssh | 2025-04-11 | N/A |
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-2011-0539 | 1 Openbsd | 1 Openssh | 2025-04-11 | N/A |
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-2014-1692 | 1 Openbsd | 1 Openssh | 2025-04-11 | N/A |
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-2008-1657 | 1 Openbsd | 1 Openssh | 2025-04-09 | N/A |
OpenSSH 4.4 up to versions before 4.9 allows remote authenticated users to bypass the sshd_config ForceCommand directive by modifying the .ssh/rc session file. | ||||
CVE-2007-2768 | 2 Netapp, Openbsd | 5 Hci Management Node, Hci Storage Node, Solidfire and 2 more | 2025-04-09 | N/A |
OpenSSH, when using OPIE (One-Time Passwords in Everything) for PAM, allows remote attackers to determine the existence of certain user accounts, which displays a different response if the user account exists and is configured to use one-time passwords (OTP), a similar issue to CVE-2007-2243. |
