CVE-2001-0144 2 Openbsd, Ssh 2 Openssh, Ssh 2025-04-03 10.0 HIGH 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-2000-1169 1 Openbsd 1 Openssh 2025-04-03 7.5 HIGH 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-2002-0083 9 Conectiva, Engardelinux, Immunix and 6 more 11 Linux, Secure Linux, Immunix and 8 more 2025-04-03 10.0 HIGH 9.8 CRITICAL
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-2001-1459 1 Openbsd 1 Openssh 2025-04-03 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-2000-0143 2 Openbsd, Ssh 2 Openssh, Ssh 2025-04-03 4.6 MEDIUM 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-2002-0640 1 Openbsd 1 Openssh 2025-04-03 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-2001-0872 3 Openbsd, Redhat, Suse 3 Openssh, Linux, Suse Linux 2025-04-03 7.2 HIGH N/A
OpenSSH 3.0.1 and earlier with UseLogin enabled does not properly cleanse critical environment variables such as LD_PRELOAD, which allows local users to gain root privileges.
CVE-2001-1029 2 Freebsd, Openbsd 2 Freebsd, Openssh 2025-04-03 2.1 LOW N/A
libutil in OpenSSH on FreeBSD 4.4 and earlier does not drop privileges before verifying the capabilities for reading the copyright and welcome files, which allows local users to bypass the capabilities checks and read arbitrary files by specifying alternate copyright or welcome files.
CVE-2004-2069 1 Openbsd 1 Openssh 2025-04-03 5.0 MEDIUM N/A
sshd.c in OpenSSH 3.6.1p2 and 3.7.1p2 and possibly other versions, when using privilege separation, does not properly signal the non-privileged process when a session has been terminated after exceeding the LoginGraceTime setting, which leaves the connection open and allows remote attackers to cause a denial of service (connection consumption).
CVE-2004-0175 1 Openbsd 1 Openssh 2025-04-03 4.3 MEDIUM N/A
Directory traversal vulnerability in scp for OpenSSH before 3.4p1 allows remote malicious servers to overwrite arbitrary files. NOTE: this may be a rediscovery of CVE-2000-0992.
CVE-2000-0217 2 Openbsd, Ssh 3 Openssh, Ssh, Ssh2 2025-04-03 5.1 MEDIUM 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-2006-0225 1 Openbsd 1 Openssh 2025-04-03 4.6 MEDIUM 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-2000-0992 2 Openbsd, Ssh 2 Openssh, Ssh 2025-04-03 5.0 MEDIUM 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 2025-04-03 10.0 HIGH N/A
Format string vulnerabilities in OpenBSD ssh program (and possibly other BSD-based operating systems) allow attackers to gain root privileges.
CVE-2006-0883 2 Freebsd, Openbsd 2 Freebsd, Openssh 2025-04-03 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-1999-1010 1 Openbsd 1 Openssh 2025-04-03 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-2003-0787 1 Openbsd 1 Openssh 2025-04-03 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.
CVE-2001-1380 1 Openbsd 1 Openssh 2025-04-03 7.5 HIGH N/A
OpenSSH before 2.9.9, while using keypairs and multiple keys of different types in the ~/.ssh/authorized_keys2 file, may not properly handle the "from" option associated with a key, which could allow remote attackers to login from unauthorized IP addresses.
CVE-2001-1507 1 Openbsd 1 Openssh 2025-04-03 7.5 HIGH N/A
OpenSSH before 3.0.1 with Kerberos V enabled does not properly authenticate users, which could allow remote attackers to login unchallenged.
CVE-2002-0639 1 Openbsd 1 Openssh 2025-04-03 10.0 HIGH 9.8 CRITICAL
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.
