| The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms.

| CVE-2011-0766 | 2 Erlang, Ssh | 3 Crypto, Erlang\/otp, Ssh | 2025-04-11 | 7.8 HIGH | N/A |
| The random number generator in the Crypto application before 2.0.2.2, and SSH before 2.0.5, as used in the Erlang/OTP ssh library before R14B03, uses predictable seeds based on the current time, which makes it easier for remote attackers to guess DSA host and SSH session keys. | |||||
| CVE-2012-5975 | 2 Linux, Ssh | 2 Linux Kernel, Tectia Server | 2025-04-11 | 9.3 HIGH | N/A |
| The SSH USERAUTH CHANGE REQUEST feature in SSH Tectia Server 6.0.4 through 6.0.20, 6.1.0 through 6.1.12, 6.2.0 through 6.2.5, and 6.3.0 through 6.3.2 on UNIX and Linux, when old-style password authentication is enabled, allows remote attackers to bypass authentication via a crafted session involving entry of blank passwords, as demonstrated by a root login session from a modified OpenSSH client with an added input_userauth_passwd_changereq call in sshconnect2.c. | |||||
| CVE-2007-2063 | 1 Ssh | 1 Tectia Server | 2025-04-09 | 4.4 MEDIUM | N/A |
| SSH Tectia Server for IBM z/OS before 5.4.0 uses insecure world-writable permissions for (1) the server pid file, which allows local users to cause arbitrary processes to be stopped, or (2) when _BPX_BATCH_UMASK is missing from the environment, creates HFS files with insecure permissions, which allows local users to read or modify these files and have other unknown impact. | |||||
| CVE-2007-5616 | 3 Linux, Opengroup, Ssh | 4 Linux Kernel, Unix, Tectia Client and 1 more | 2025-04-09 | 7.2 HIGH | N/A |
| ssh-signer in SSH Tectia Client and Server 5.x before 5.2.4, and 5.3.x before 5.3.6, on Unix and Linux allows local users to gain privileges via unspecified vectors. | |||||
| CVE-2006-5484 | 1 Ssh | 4 Tectia Client, Tectia Connector, Tectia Manager and 1 more | 2025-04-09 | 5.0 MEDIUM | N/A |
| SSH Tectia Client/Server/Connector 5.1.0 and earlier, Manager 2.2.0 and earlier, and other products, when using an RSA key with exponent 3, removes PKCS-1 padding before generating a hash, which allows remote attackers to forge a PKCS #1 v1.5 signature that is signed by that RSA key and prevents Tectia from correctly verifying X.509 and other certificates that use PKCS #1, a similar issue to CVE-2006-4339. | |||||
| CVE-2008-5161 | 2 Openbsd, Ssh | 5 Openssh, Tectia Client, Tectia Connector and 2 more | 2025-04-09 | 2.6 LOW | 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-2001-0471 | 1 Ssh | 1 Ssh | 2025-04-03 | 7.5 HIGH | N/A |
| SSH daemon version 1 (aka SSHD-1 or SSH-1) 1.2.30 and earlier does not log repeated login attempts, which could allow remote attackers to compromise accounts without detection via a brute force attack. | |||||
| CVE-2002-1715 | 1 Ssh | 2 Ssh, Ssh2 | 2025-04-03 | 7.2 HIGH | N/A |
| SSH 1 through 3, and possibly other versions, allows local users to bypass restricted shells such as rbash or rksh by uploading a script to a world-writeable directory, then executing that script to gain normal shell access. | |||||
| CVE-2001-1473 | 1 Ssh | 1 Ssh | 2025-04-03 | 7.5 HIGH | N/A |
| The SSH-1 protocol allows remote servers to conduct man-in-the-middle attacks and replay a client challenge response to a target server by creating a Session ID that matches the Session ID of the target, but which uses a public key pair that is weaker than the target's public key, which allows the attacker to compute the corresponding private key and use the target's Session ID with the compromised key pair to masquerade as the target. | |||||
| CVE-2001-0553 | 1 Ssh | 1 Secure Shell | 2025-04-03 | 7.2 HIGH | N/A |
| SSH Secure Shell 3.0.0 on Unix systems does not properly perform password authentication to the sshd2 daemon, which allows local users to gain access to accounts with short password fields, such as locked accounts that use "NP" in the password field. | |||||
| CVE-2002-1645 | 1 Ssh | 1 Ssh2 | 2025-04-03 | 10.0 HIGH | N/A |
| Buffer overflow in the URL catcher feature for SSH Secure Shell for Workstations client 3.1 to 3.2.0 allows remote attackers to execute arbitrary code via a long URL. | |||||
