CVE-2008-3844 | 2 Openbsd, Redhat | 3 Openssh, Enterprise Linux, Enterprise Linux Desktop | 2017-08-07 | 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-2008-3259 | 1 Openbsd | 1 Openssh | 2017-08-07 | 1.2 LOW | N/A |
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. | |||||
CVE-2007-2243 | 1 Openbsd | 1 Openssh | 2017-07-28 | 5.0 MEDIUM | N/A |
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. | |||||
CVE-2001-1585 | 1 Openbsd | 1 Openssh | 2017-07-28 | 6.8 MEDIUM | N/A |
SSH protocol 2 (aka SSH-2) public key authentication in the development snapshot of OpenSSH 2.3.1, available from 2001-01-18 through 2001-02-08, does not perform a challenge-response step to ensure that the client has the proper private key, which allows remote attackers to bypass authentication as other users by supplying a public key from that user's authorized_keys file. | |||||
CVE-2006-0883 | 2 Freebsd, Openbsd | 2 Freebsd, Openssh | 2017-07-19 | 5.0 MEDIUM | N/A |
OpenSSH on FreeBSD 5.3 and 5.4, when used with OpenPAM, does not properly handle when a forked child process terminates during PAM authentication, which allows remote attackers to cause a denial of service (client connection refusal) by connecting multiple times to the SSH server, waiting for the password prompt, then disconnecting. | |||||
CVE-2004-1653 | 1 Openbsd | 1 Openssh | 2017-07-10 | 6.4 MEDIUM | N/A |
The default configuration for OpenSSH enables AllowTcpForwarding, which could allow remote authenticated users to perform a port bounce, when configured with an anonymous access program such as AnonCVS. | |||||
CVE-2001-1459 | 1 Openbsd | 1 Openssh | 2017-07-10 | 7.5 HIGH | N/A |
OpenSSH 2.9 and earlier does not initiate a Pluggable Authentication Module (PAM) session if commands are executed with no pty, which allows local users to bypass resource limits (rlimits) set in pam.d. | |||||
CVE-2014-2653 | 1 Openbsd | 1 Openssh | 2017-01-06 | 5.8 MEDIUM | 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-2005-2797 | 1 Openbsd | 1 Openssh | 2016-12-07 | 5.0 MEDIUM | N/A |
OpenSSH 4.0, and other versions before 4.2, does not properly handle dynamic port forwarding ("-D" option) when a listen address is not provided, which may cause OpenSSH to enable the GatewayPorts functionality. | |||||
CVE-2002-0639 | 1 Openbsd | 1 Openssh | 2016-10-17 | 10.0 HIGH | N/A |
Integer overflow in sshd in OpenSSH 2.9.9 through 3.3 allows remote attackers to execute arbitrary code during challenge response authentication (ChallengeResponseAuthentication) when OpenSSH is using SKEY or BSD_AUTH authentication. | |||||
CVE-2002-0575 | 1 Openbsd | 1 Openssh | 2016-10-17 | 7.5 HIGH | N/A |
Buffer overflow in OpenSSH before 2.9.9, and 3.x before 3.2.1, with Kerberos/AFS support and KerberosTgtPassing or AFSTokenPassing enabled, allows remote and local authenticated users to gain privileges. | |||||
CVE-2002-0640 | 1 Openbsd | 1 Openssh | 2016-10-17 | 10.0 HIGH | N/A |
Buffer overflow in sshd in OpenSSH 2.3.1 through 3.3 may allow remote attackers to execute arbitrary code via a large number of responses during challenge response authentication when OpenBSD is using PAM modules with interactive keyboard authentication (PAMAuthenticationViaKbdInt). | |||||
CVE-2002-0083 | 9 Conectiva, Engardelinux, Immunix and 6 more | 11 Linux, Secure Linux, Immunix and 8 more | 2016-10-17 | 10.0 HIGH | N/A |
Off-by-one error in the channel code of OpenSSH 2.0 through 3.0.2 allows local users or remote malicious servers to gain privileges. | |||||
CVE-1999-1010 | 1 Openbsd | 1 Openssh | 2016-10-17 | 2.1 LOW | N/A |
An SSH 1.2.27 server allows a client to use the "none" cipher, even if it is not allowed by the server policy. | |||||
CVE-2010-4755 | 3 Freebsd, Netbsd, Openbsd | 4 Freebsd, Netbsd, Openbsd and 1 more | 2014-08-08 | 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 | 2014-02-21 | 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-2011-5000 | 1 Openbsd | 1 Openssh | 2012-07-21 | 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-2004-2760 | 1 Openbsd | 1 Openssh | 2009-01-28 | 6.8 MEDIUM | N/A |
sshd in OpenSSH 3.5p1, when PermitRootLogin is disabled, immediately closes the TCP connection after a root login attempt with the correct password, but leaves the connection open after an attempt with an incorrect password, which makes it easier for remote attackers to guess the password by observing the connection state, a different vulnerability than CVE-2003-0190. NOTE: it could be argued that in most environments, this does not cross privilege boundaries without requiring leverage of a separate vulnerability. | |||||
CVE-2003-0786 | 1 Openbsd | 1 Openssh | 2008-09-10 | 10.0 HIGH | N/A |
The SSH1 PAM challenge response authentication in OpenSSH 3.7.1 and 3.7.1p1, when Privilege Separation is disabled, does not check the result of the authentication attempt, which can allow remote attackers to gain privileges. | |||||
CVE-2003-0787 | 1 Openbsd | 1 Openssh | 2008-09-10 | 7.5 HIGH | N/A |
The PAM conversation function in OpenSSH 3.7.1 and 3.7.1p1 interprets an array of structures as an array of pointers, which allows attackers to modify the stack and possibly gain privileges. |
