|---|---|---|---|---|---|
| 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-2015-5600 | 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-2016-6515 | 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-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-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-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-2010-4755 | 3 Freebsd, Netbsd, Openbsd | 4 Freebsd, Netbsd, Openbsd and 1 more | 2025-04-11 | 4.0 MEDIUM | 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-2011-4327 | 1 Openbsd | 1 Openssh | 2025-04-11 | 2.1 LOW | 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-2010-4478 | 1 Openbsd | 1 Openssh | 2025-04-11 | 7.5 HIGH | 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-2012-0814 | 1 Openbsd | 1 Openssh | 2025-04-11 | 3.5 LOW | 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-2014-1692 | 1 Openbsd | 1 Openssh | 2025-04-11 | 7.5 HIGH | 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-2011-0539 | 1 Openbsd | 1 Openssh | 2025-04-11 | 5.0 MEDIUM | 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-2011-5000 | 1 Openbsd | 1 Openssh | 2025-04-11 | 3.5 LOW | 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-2013-4548 | 1 Openbsd | 1 Openssh | 2025-04-11 | 6.0 MEDIUM | 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-2010-5107 | 1 Openbsd | 1 Openssh | 2025-04-11 | 5.0 MEDIUM | 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-2025-26466 | 3 Canonical, Debian, Openbsd | 3 Ubuntu Linux, Debian Linux, Openssh | 2025-04-10 | N/A | 5.9 MEDIUM |
| A flaw was found in the OpenSSH package. For each ping packet the SSH server receives, a pong packet is allocated in a memory buffer and stored in a queue of packages. It is only freed when the server/client key exchange has finished. A malicious client may keep sending such packages, leading to an uncontrolled increase in memory consumption on the server side. Consequently, the server may become unavailable, resulting in a denial of service attack. | |||||
| CVE-2007-4752 | 1 Openbsd | 1 Openssh | 2025-04-09 | 7.5 HIGH | N/A |
| ssh in OpenSSH before 4.7 does not properly handle when an untrusted cookie cannot be created and uses a trusted X11 cookie instead, which allows attackers to violate intended policy and gain privileges by causing an X client to be treated as trusted. | |||||
| CVE-2008-1657 | 1 Openbsd | 1 Openssh | 2025-04-09 | 6.5 MEDIUM | 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-2007-3102 | 2 Fedora Project, Openbsd | 2 Fedora Core, Openssh | 2025-04-09 | 4.3 MEDIUM | 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-2008-4109 | 2 Debian, Openbsd | 2 Linux, Openssh | 2025-04-09 | 5.0 MEDIUM | N/A |
| A certain Debian patch for OpenSSH before 4.3p2-9etch3 on etch; before 4.6p1-1 on sid and lenny; and on other distributions such as SUSE uses functions that are not async-signal-safe in the signal handler for login timeouts, which allows remote attackers to cause a denial of service (connection slot exhaustion) via multiple login attempts. NOTE: this issue exists because of an incorrect fix for CVE-2006-5051. | |||||
