Vuln ID Summary CVSS Severity
CVE-2016-10011

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.

V3.0: 5.5 MEDIUM
V2.0: 2.1 LOW
CVE-2016-10010

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.

Published: January 04, 2017; 9:59:03 PM -0500
V3.0: 7.0 HIGH
V2.0: 6.9 MEDIUM
CVE-2016-10009

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.

Published: January 04, 2017; 9:59:03 PM -0500
V3.0: 7.3 HIGH
V2.0: 7.5 HIGH
CVE-2016-3115

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.

V3.0: 6.4 MEDIUM
V2.0: 5.5 MEDIUM
CVE-2016-0778

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.

Published: January 14, 2016; 5:59:02 PM -0500
V3.0: 8.1 HIGH
V2.0: 4.6 MEDIUM
CVE-2016-0777

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.

Published: January 14, 2016; 5:59:01 PM -0500
V3.0: 6.5 MEDIUM
V2.0: 4.0 MEDIUM
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.

Published: August 23, 2015; 9:59:01 PM -0400
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.

Published: August 23, 2015; 9:59:00 PM -0400
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
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
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
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
V3.0: 4.9 MEDIUM
V2.0: 5.8 MEDIUM
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.

V2.0: 7.5 HIGH
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.

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.
