| CVE-2006-5229 | 2 Novell, Openbsd | 2 Suse Linux, Openssh | 2024-08-07 | N/A |
| OpenSSH portable 4.1 on SUSE Linux, and possibly other platforms and versions, and possibly under limited configurations, allows remote attackers to determine valid usernames via timing discrepancies in which responses take longer for valid usernames than invalid ones, as demonstrated by sshtime. NOTE: as of 20061014, it appears that this issue is dependent on the use of manually-set passwords that causes delays when processing /etc/shadow due to an increased number of rounds. | ||||
| CVE-2006-5051 | 4 Apple, Debian, Openbsd and 1 more | 5 Mac Os X, Mac Os X Server, Debian Linux and 2 more | 2024-08-07 | 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-2006-5052 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2024-08-07 | 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." | ||||
| CVE-2006-4924 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2024-08-07 | N/A |
| sshd in OpenSSH before 4.4, when using the version 1 SSH protocol, allows remote attackers to cause a denial of service (CPU consumption) via an SSH packet that contains duplicate blocks, which is not properly handled by the CRC compensation attack detector. | ||||
| CVE-2006-4925 | 1 Openbsd | 1 Openssh | 2024-08-07 | 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-2006-0883 | 2 Freebsd, Openbsd | 2 Freebsd, Openssh | 2024-08-07 | 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-2006-0225 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2024-08-07 | N/A |
| scp in OpenSSH 4.2p1 allows attackers to execute arbitrary commands via filenames that contain shell metacharacters or spaces, which are expanded twice. | ||||
| CVE-2007-4752 | 2 Openbsd, Redhat | 3 Openssh, Enterprise Linux, Rhel Eus | 2024-08-07 | 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-2007-4654 | 3 Cisco, Openbsd, Teamf1 | 4 Content Services Switch 11000, Webns, Openssh and 1 more | 2024-08-07 | N/A |
| Unspecified vulnerability in SSHield 1.6.1 with OpenSSH 3.0.2p1 on Cisco WebNS 8.20.0.1 on Cisco Content Services Switch (CSS) series 11000 devices allows remote attackers to cause a denial of service (connection slot exhaustion and device crash) via a series of large packets designed to exploit the SSH CRC32 attack detection overflow (CVE-2001-0144), possibly a related issue to CVE-2002-1024. | ||||
| CVE-2007-3102 | 3 Fedora Project, Openbsd, Redhat | 3 Fedora Core, Openssh, Enterprise Linux | 2024-08-07 | 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-2007-2768 | 2 Netapp, Openbsd | 5 Hci Management Node, Hci Storage Node, Solidfire and 2 more | 2024-08-07 | N/A |
| 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. | ||||
| CVE-2007-2243 | 1 Openbsd | 1 Openssh | 2024-08-07 | 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-2008-5161 | 3 Openbsd, Redhat, Ssh | 6 Openssh, Enterprise Linux, Tectia Client and 3 more | 2024-08-07 | N/A |
| Error handling in the SSH protocol in (1) SSH Tectia Client and Server and Connector 4.0 through 4.4.11, 5.0 through 5.2.4, and 5.3 through 5.3.8; Client and Server and ConnectSecure 6.0 through 6.0.4; Server for Linux on IBM System z 6.0.4; Server for IBM z/OS 5.5.1 and earlier, 6.0.0, and 6.0.1; and Client 4.0-J through 4.3.3-J and 4.0-K through 4.3.10-K; and (2) OpenSSH 4.7p1 and possibly other versions, when using a block cipher algorithm in Cipher Block Chaining (CBC) mode, makes it easier for remote attackers to recover certain plaintext data from an arbitrary block of ciphertext in an SSH session via unknown vectors. | ||||
| CVE-2008-4109 | 2 Debian, Openbsd | 2 Linux, Openssh | 2024-08-07 | 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. | ||||
| CVE-2008-3844 | 2 Openbsd, Redhat | 4 Openssh, Enterprise Linux, Enterprise Linux Desktop and 1 more | 2024-08-07 | 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 | 2024-08-07 | 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-2008-3234 | 2 Debian, Openbsd | 2 Debian Linux, Openssh | 2024-08-07 | N/A |
| sshd in OpenSSH 4 on Debian GNU/Linux, and the 20070303 OpenSSH snapshot, allows remote authenticated users to obtain access to arbitrary SELinux roles by appending a :/ (colon slash) sequence, followed by the role name, to the username. | ||||
| CVE-2008-1657 | 1 Openbsd | 1 Openssh | 2024-08-07 | 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-2008-1483 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2024-08-07 | N/A |
| OpenSSH 4.3p2, and probably other versions, allows local users to hijack forwarded X connections by causing ssh to set DISPLAY to :10, even when another process is listening on the associated port, as demonstrated by opening TCP port 6010 (IPv4) and sniffing a cookie sent by Emacs. | ||||
| CVE-2009-2904 | 3 Fedoraproject, Openbsd, Redhat | 5 Fedora, Openssh, Enterprise Linux and 2 more | 2024-08-07 | N/A |
| A certain Red Hat modification to the ChrootDirectory feature in OpenSSH 4.8, as used in sshd in OpenSSH 4.3 in Red Hat Enterprise Linux (RHEL) 5.4 and Fedora 11, allows local users to gain privileges via hard links to setuid programs that use configuration files within the chroot directory, related to requirements for directory ownership. | ||||
