2023-12-18 CVE-2023-51384 In ssh-agent in OpenSSH before 9.6, certain destination constraints can be incompletely applied. When destination constraints are specified during addition of PKCS#11-hosted private keys, these constraints are only applied to the first key, even if a PKCS#11 token returns multiple keys. Debian_linux, Openssh 5.5
2023-12-18 CVE-2023-48795 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...

2023-07-20 CVE-2023-38408 The PKCS#11 feature in ssh-agent in OpenSSH before 9.3p2 has an insufficiently trustworthy search path, leading to remote code execution if an agent is forwarded to an attacker-controlled system. (Code in /usr/lib is not necessarily safe for loading into ssh-agent.) NOTE: this issue exists because of an incomplete fix for CVE-2016-10009. Fedora, Openssh 9.8
2023-12-18 CVE-2023-51385 In ssh in OpenSSH before 9.6, OS command injection might occur if a user name or host name has shell metacharacters, and this name is referenced by an expansion token in certain situations. For example, an untrusted Git repository can have a submodule with shell metacharacters in a user name or host name. Debian_linux, Openssh 6.5
2023-02-03 CVE-2023-25136 OpenSSH server (sshd) 9.1 introduced a double-free vulnerability during options.kex_algorithms handling. This is fixed in OpenSSH 9.2. The double free can be leveraged, by an unauthenticated remote attacker in the default configuration, to jump to any location in the sshd address space. One third-party report states "remote code execution is theoretically possible." Fedora, 500f_firmware, A250_firmware, C250_firmware, Ontap_select_deploy_administration_utility, Openssh 6.5
2023-12-24 CVE-2023-51767 OpenSSH through 9.6, when common types of DRAM are used, might allow row hammer attacks (for authentication bypass) because the integer value of authenticated in mm_answer_authpassword does not resist flips of a single bit. NOTE: this is applicable to a certain threat model of attacker-victim co-location in which the attacker has user privileges. Fedora, Openssh, Enterprise_linux 7.0
2003-05-12 CVE-2003-0190 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. Openssh, Openpkg, Scalance_x204rna_ecc_firmware, Scalance_x204rna_firmware N/A
2023-03-17 CVE-2023-28531 ssh-add in OpenSSH before 9.3 adds smartcard keys to ssh-agent without the intended per-hop destination constraints. The earliest affected version is 8.9. Brocade_fabric_operating_system, Hci_bootstrap_os, Solidfire_element_os, Openssh 9.8
2002-07-03 CVE-2002-0639 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. Openssh 9.8
2002-03-15 CVE-2002-0083 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. Linux, Secure_linux, Immunix, Mandrake_linux, Mandrake_linux_corporate_server, Mandrake_single_network_firewall, Openssh, Openpkg, Linux, Suse_linux, Secure_linux 9.8
