CVE-2008-4109 2 Debian, Openbsd 2 Linux, Openssh 2025-04-09 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-2006-5794 2 Openbsd, Redhat 2 Openssh, Enterprise Linux 2025-04-09 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-2003-0787 1 Openbsd 1 Openssh 2025-04-03 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.
CVE-2003-0786 1 Openbsd 1 Openssh 2025-04-03 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-2005-2798 2 Openbsd, Redhat 2 Openssh, Enterprise Linux 2025-04-03 N/A
sshd in OpenSSH before 4.2, when GSSAPIDelegateCredentials is enabled, allows GSSAPI credentials to be delegated to clients who log in using non-GSSAPI methods, which could cause those credentials to be exposed to untrusted users or hosts.
CVE-2000-0525 1 Openbsd 1 Openssh 2025-04-03 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-2003-0682 2 Openbsd, Redhat 3 Openssh, Enterprise Linux, Linux 2025-04-03 N/A
"Memory bugs" in OpenSSH 3.7.1 and earlier, with unknown impact, a different set of vulnerabilities than CVE-2003-0693 and CVE-2003-0695.
CVE-2006-0883 2 Freebsd, Openbsd 2 Freebsd, Openssh 2025-04-03 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-2001-0144 2 Openbsd, Ssh 2 Openssh, Ssh 2025-04-03 N/A
CORE SDI SSH1 CRC-32 compensation attack detector allows remote attackers to execute arbitrary commands on an SSH server or client via an integer overflow.
CVE-2004-1653 1 Openbsd 1 Openssh 2025-04-03 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-2003-0693 2 Openbsd, Redhat 3 Openssh, Enterprise Linux, Linux 2025-04-03 N/A
A "buffer management error" in buffer_append_space of buffer.c for OpenSSH before 3.7 may allow remote attackers to execute arbitrary code by causing an incorrect amount of memory to be freed and corrupting the heap, a different vulnerability than CVE-2003-0695.
CVE-2005-2666 2 Openbsd, Redhat 2 Openssh, Enterprise Linux 2025-04-03 N/A
SSH, as implemented in OpenSSH before 4.0 and possibly other implementations, stores hostnames, IP addresses, and keys in plaintext in the known_hosts file, which makes it easier for an attacker that has compromised an SSH user's account to generate a list of additional targets that are more likely to have the same password or key.
CVE-2002-0765 1 Openbsd 2 Openbsd, Openssh 2025-04-03 N/A
sshd in OpenSSH 3.2.2, when using YP with netgroups and under certain conditions, may allow users to successfully authenticate and log in with another user's password.
CVE-2000-1169 1 Openbsd 1 Openssh 2025-04-03 N/A
OpenSSH SSH client before 2.3.0 does not properly disable X11 or agent forwarding, which could allow a malicious SSH server to gain access to the X11 display and sniff X11 events, or gain access to the ssh-agent.
CVE-2003-0190 4 Openbsd, Openpkg, Redhat and 1 more 8 Openssh, Openpkg, Enterprise Linux and 5 more 2025-04-03 N/A
OpenSSH-portable (OpenSSH) 3.6.1p1 and earlier with PAM support enabled immediately sends an error message when a user does not exist, which allows remote attackers to determine valid usernames via a timing attack.
CVE-2000-0217 2 Openbsd, Ssh 3 Openssh, Ssh, Ssh2 2025-04-03 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-2000-0143 2 Openbsd, Ssh 2 Openssh, Ssh 2025-04-03 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-2000-0999 1 Openbsd 1 Openssh 2025-04-03 N/A
Format string vulnerabilities in OpenBSD ssh program (and possibly other BSD-based operating systems) allow attackers to gain root privileges.
CVE-1999-1010 1 Openbsd 1 Openssh 2025-04-03 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-2003-1562 1 Openbsd 1 Openssh 2025-04-03 N/A
sshd in OpenSSH 3.6.1p2 and earlier, when PermitRootLogin is disabled and using PAM keyboard-interactive authentication, does not insert a delay after a root login attempt with the correct password, which makes it easier for remote attackers to use timing differences to determine if the password step of a multi-step authentication is successful, a different vulnerability than CVE-2003-0190.
