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...

2020-06-29 CVE-2020-14145 The client side in OpenSSH 5.7 through 8.4 has an Observable Discrepancy leading to an information leak in the algorithm negotiation. This allows man-in-the-middle attackers to target initial connection attempts (where no host key for the server has been cached by the client). NOTE: some reports state that 8.5 and 8.6 are also affected. Active_iq_unified_manager, Aff_a700s_firmware, Hci_compute_node, Hci_management_node, Hci_storage_node, Ontap_select_deploy_administration_utility, Solidfire, Steelstore_cloud_integrated_storage, Openssh 5.9
2020-07-24 CVE-2020-15778 scp in OpenSSH through 8.3p1 allows command injection in the scp.c toremote function, as demonstrated by backtick characters in the destination argument. NOTE: the vendor reportedly has stated that they intentionally omit validation of "anomalous argument transfers" because that could "stand a great chance of breaking existing workflows." Fabric_operating_system, A700s_firmware, Active_iq_unified_manager, Hci_compute_node, Hci_management_node, Hci_storage_node, Solidfire, Steelstore_cloud_integrated_storage, Openssh 7.8
2021-03-05 CVE-2021-28041 ssh-agent in OpenSSH before 8.5 has a double free that may be relevant in a few less-common scenarios, such as unconstrained agent-socket access on a legacy operating system, or the forwarding of an agent to an attacker-controlled host. Fedora, Cloud_backup, Hci_compute_node_firmware, Hci_management_node, Hci_storage_node_firmware, Solidfire, Openssh, Communications_offline_mediation_controller, Zfs_storage_appliance 7.1
2021-09-26 CVE-2021-41617 sshd in OpenSSH 6.2 through 8.x before 8.8, when certain non-default configurations are used, allows privilege escalation because supplemental groups are not initialized as expected. Helper programs for AuthorizedKeysCommand and AuthorizedPrincipalsCommand may run with privileges associated with group memberships of the sshd process, if the configuration specifies running the command as a different user. Fedora, Active_iq_unified_manager, Aff_500f_firmware, Aff_a250_firmware, Clustered_data_ontap, Hci_management_node, Ontap_select_deploy_administration_utility, Solidfire, Openssh, Http_server, Zfs_storage_appliance_kit, Starwind_virtual_san 7.0
2022-03-13 CVE-2021-36368 An issue was discovered in OpenSSH before 8.9. If a client is using public-key authentication with agent forwarding but without -oLogLevel=verbose, and an attacker has silently modified the server to support the None authentication option, then the user cannot determine whether FIDO authentication is going to confirm that the user wishes to connect to that server, or that the user wishes to allow that server to connect to a different server on the user's behalf. NOTE: the vendor's position... Debian_linux, Openssh 3.7
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
2023-03-17 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
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-2023-51384 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
