CVE-2015-6564 |
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.

V4.0:(not available) V3.x:(not available) V2.0: 6.9 MEDIUM |
CVE-2015-6563 |
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.

V4.0:(not available) V3.x:(not available) V2.0: 1.9 LOW |
CVE-2015-5600 |
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. Published: August 02, 2015; 9:59:03 PM -0400 |
V4.0:(not available) V3.x:(not available) V2.0: 8.5 HIGH |
CVE-2015-5352 |
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. Published: August 02, 2015; 9:59:01 PM -0400 |
V4.0:(not available) V3.x:(not available) V2.0: 4.3 MEDIUM |
CVE-2014-2653 |
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. Published: March 27, 2014; 6:55:04 AM -0400 |
V4.0:(not available) V3.x:(not available) V2.0: 5.8 MEDIUM |
CVE-2014-2532 |
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. Published: March 18, 2014; 1:18:19 AM -0400 |
V4.0:(not available) V3.0: 4.9 MEDIUM V2.0: 5.8 MEDIUM |
CVE-2011-4327 |
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. Published: February 02, 2014; 10:55:03 PM -0500 |
V4.0:(not available) V3.x:(not available) V2.0: 2.1 LOW |
CVE-2014-1692 |
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. Published: January 29, 2014; 11:02:05 AM -0500 |
V4.0:(not available) V3.x:(not available) V2.0: 7.5 HIGH |
CVE-2010-5107 |
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. Published: March 07, 2013; 3:55:01 PM -0500 |
V4.0:(not available) V3.x:(not available) V2.0: 5.0 MEDIUM |
CVE-2011-5000 |
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. Published: April 05, 2012; 10:55:03 AM -0400 |
V4.0:(not available) V3.x:(not available) V2.0: 3.5 LOW |
CVE-2012-0814 |
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. Published: January 27, 2012; 2:55:01 PM -0500 |
V4.0:(not available) V3.x:(not available) V2.0: 3.5 LOW |
CVE-2010-4755 |
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. Published: March 02, 2011; 3:00:00 PM -0500 |
V4.0:(not available) V3.x:(not available) V2.0: 4.0 MEDIUM |
CVE-2010-4478 |
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. Published: December 06, 2010; 5:30:31 PM -0500 |
V4.0:(not available) V3.x:(not available) V2.0: 7.5 HIGH |
CVE-2008-4109 |
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. Published: September 18, 2008; 11:04:27 AM -0400 |
V4.0:(not available) V3.x:(not available) V2.0: 5.0 MEDIUM |
CVE-2008-3844 |
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. Published: August 27, 2008; 4:41:00 PM -0400 |
V4.0:(not available) V3.x:(not available) V2.0: 9.3 HIGH |
CVE-2008-3259 |
OpenSSH before 5.1 sets the SO_REUSEADDR socket option when the X11UseLocalhost configuration setting is disabled, which allows local users on some platforms to hijack the X11 forwarding port via a bind to a single IP address, as demonstrated on the HP-UX platform. Published: July 22, 2008; 12:41:00 PM -0400 |
V4.0:(not available) V3.x:(not available) V2.0: 1.2 LOW |
CVE-2008-1657 |
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. Published: April 02, 2008; 2:44:00 PM -0400 |
V4.0:(not available) V3.x:(not available) V2.0: 6.5 MEDIUM |
CVE-2007-4752 |
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. Published: September 11, 2007; 9:17:00 PM -0400 |
V4.0:(not available) V3.x:(not available) V2.0: 7.5 HIGH |
CVE-2007-2768 |
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. Published: May 21, 2007; 4:30:00 PM -0400 |
V4.0:(not available) V3.x:(not available) V2.0: 4.3 MEDIUM |
CVE-2007-2243 |
OpenSSH 4.6 and earlier, when ChallengeResponseAuthentication is enabled, allows remote attackers to determine the existence of user accounts by attempting to authenticate via S/KEY, which displays a different response if the user account exists, a similar issue to CVE-2001-1483.
