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-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-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-2016-0778 | 5 Apple, Hp, Openbsd and 2 more | 6 Mac Os X, Virtual Customer Access System, Openssh and 3 more | 2025-04-12 | 4.6 MEDIUM | 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-2016-10011 | 1 Openbsd | 1 Openssh | 2025-04-12 | 2.1 LOW | 5.5 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-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-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-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-2010-5107 | 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-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-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-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-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-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-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-2008-3844 | 2 Openbsd, Redhat | 3 Openssh, Enterprise Linux, Enterprise Linux Desktop | 2025-04-09 | 9.3 HIGH | N/A |
Certain Red Hat Enterprise Linux (RHEL) 4 and 5 packages for OpenSSH, as signed in August 2008 using a legitimate Red Hat GPG key, contain an externally introduced modification (Trojan Horse) that allows the package authors to have an unknown impact. NOTE: since the malicious packages were not distributed from any official Red Hat sources, the scope of this issue is restricted to users who may have obtained these packages through unofficial distribution points. As of 20080827, no unofficial distributions of this software are known. | |||||
CVE-2006-5051 | 3 Apple, Debian, Openbsd | 4 Mac Os X, Mac Os X Server, Debian Linux and 1 more | 2025-04-09 | 9.3 HIGH | 8.1 HIGH |
Signal handler race condition in OpenSSH before 4.4 allows remote attackers to cause a denial of service (crash), and possibly execute arbitrary code if GSSAPI authentication is enabled, via unspecified vectors that lead to a double-free. | |||||
CVE-2006-4925 | 1 Openbsd | 1 Openssh | 2025-04-09 | 5.0 MEDIUM | N/A |
packet.c in ssh in OpenSSH allows remote attackers to cause a denial of service (crash) by sending an invalid protocol sequence with USERAUTH_SUCCESS before NEWKEYS, which causes newkeys[mode] to be NULL. | |||||
CVE-2006-5052 | 1 Openbsd | 1 Openssh | 2025-04-09 | 5.0 MEDIUM | N/A |
Unspecified vulnerability in portable OpenSSH before 4.4, when running on some platforms, allows remote attackers to determine the validity of usernames via unknown vectors involving a GSSAPI "authentication abort." |
