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-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-2008-3844 2 Openbsd, Redhat 4 Openssh, Enterprise Linux, Enterprise Linux Desktop and 1 more 2026-04-23 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 2026-04-23 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 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-2008-1657 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-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-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-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-2006-5052 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-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-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-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-1999-1010 1 Openbsd 1 Openssh 2026-04-16 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-2001-1459 1 Openbsd 1 Openssh 2026-04-16 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-2001-1382 1 Openbsd 1 Openssh 2026-04-16 N/A
The "echo simulation" traffic analysis countermeasure in OpenSSH before 2.9.9p2 sends an additional echo packet after the password and carriage return is entered, which could allow remote attackers to determine that the countermeasure is being used.
CVE-2001-1380 2 Openbsd, Redhat 2 Openssh, Linux 2026-04-16 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-2001-1029 2 Freebsd, Openbsd 2 Freebsd, Openssh 2026-04-16 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.
