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
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
2023-12-24 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
2024-07-01 CVE-2024-6387 A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd). There is a race condition which can lead sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a set time period. Linux_2023, Ubuntu_linux, Debian_linux, Freebsd, E\-Series_santricity_os_controller, Ontap_select_deploy_administration_utility, Ontap_tools, Netbsd, Openssh, Enterprise_linux, Enterprise_linux_eus, Enterprise_linux_for_arm_64, Enterprise_linux_for_arm_64_eus, Enterprise_linux_for_ibm_z_systems, Enterprise_linux_for_ibm_z_systems_eus, Enterprise_linux_for_power_little_endian, Enterprise_linux_for_power_little_endian_eus, Enterprise_linux_server_aus, Openshift_container_platform, Linux_enterprise_micro 8.1
2016-12-09 CVE-2016-8858 The kex_input_kexinit function in kex.c in OpenSSH 6.x and 7.x through 7.3 allows remote attackers to cause a denial of service (memory consumption) by sending many duplicate KEXINIT requests. NOTE: a third party reports that "OpenSSH upstream does not consider this as a security issue." Openssh 7.5
