CVE-2008-3234 2 Debian, Openbsd 2 Debian Linux, Openssh 2026-04-23 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-2008-4109 2 Debian, Openbsd 2 Linux, Openssh 2026-04-23 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-2008-1657 1 Openbsd 1 Openssh 2026-04-23 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 2026-04-23 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-2006-4924 2 Openbsd, Redhat 2 Openssh, Enterprise Linux 2026-04-23 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-2007-4752 2 Openbsd, Redhat 3 Openssh, Enterprise Linux, Rhel Eus 2026-04-23 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-2006-5051 4 Apple, Debian, Openbsd and 1 more 5 Mac Os X, Mac Os X Server, Debian Linux and 2 more 2026-04-23 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-2007-4654 3 Cisco, Openbsd, Teamf1 4 Content Services Switch 11000, Webns, Openssh and 1 more 2026-04-23 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 2026-04-23 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 2026-04-23 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 2026-04-23 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-2006-4925 1 Openbsd 1 Openssh 2026-04-23 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-2006-5794 2 Openbsd, Redhat 2 Openssh, Enterprise Linux 2026-04-23 N/A
Unspecified vulnerability in the sshd Privilege Separation Monitor in OpenSSH before 4.5 causes weaker verification that authentication has been successful, which might allow attackers to bypass authentication. NOTE: as of 20061108, it is believed that this issue is only exploitable by leveraging vulnerabilities in the unprivileged process, which are not known to exist.
CVE-2006-5052 2 Openbsd, Redhat 2 Openssh, Enterprise Linux 2026-04-23 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-2006-0883 2 Freebsd, Openbsd 2 Freebsd, Openssh 2026-04-16 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-2000-0143 2 Openbsd, Ssh 2 Openssh, Ssh 2026-04-16 N/A
The SSH protocol server sshd allows local users without shell access to redirect a TCP connection through a service that uses the standard system password database for authentication, such as POP or FTP.
CVE-2000-0217 2 Openbsd, Ssh 3 Openssh, Ssh, Ssh2 2026-04-16 N/A
The default configuration of SSH allows X forwarding, which could allow a remote attacker to control a client's X sessions via a malicious xauth program.
CVE-2000-0525 1 Openbsd 1 Openssh 2026-04-16 N/A
OpenSSH does not properly drop privileges when the UseLogin option is enabled, which allows local users to execute arbitrary commands by providing the command to the ssh daemon.
CVE-2000-0992 2 Openbsd, Ssh 2 Openssh, Ssh 2026-04-16 N/A
Directory traversal vulnerability in scp in sshd 1.2.xx allows a remote malicious scp server to overwrite arbitrary files via a .. (dot dot) attack.
CVE-2000-0999 1 Openbsd 1 Openssh 2026-04-16 N/A
Format string vulnerabilities in OpenBSD ssh program (and possibly other BSD-based operating systems) allow attackers to gain root privileges.
