Date Id Summary Products Score Patch Annotated
2016-08-07 CVE-2016-6515 The auth_password function in auth-passwd.c in sshd in OpenSSH before 7.3 does not limit password lengths for password authentication, which allows remote attackers to cause a denial of service (crypt CPU consumption) via a long string. Fedora, Openssh 7.5
2017-01-05 CVE-2016-10011 authfile.c in sshd in OpenSSH before 7.4 does not properly consider the effects of realloc on buffer contents, which might allow local users to obtain sensitive private-key information by leveraging access to a privilege-separated child process. Openssh 5.5
2018-01-21 CVE-2016-10708 sshd in OpenSSH before 7.4 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an out-of-sequence NEWKEYS message, as demonstrated by Honggfuzz, related to kex.c and packet.c. Ubuntu_linux, Debian_linux, Cloud_backup, Clustered_data_ontap, Data_ontap, Data_ontap_edge, Oncommand_unified_manager, Service_processor, Storagegrid, Storagegrid_webscale, Vasa_provider, Openssh 7.5
2019-10-09 CVE-2019-16905 OpenSSH 7.7 through 7.9 and 8.x before 8.1, when compiled with an experimental key type, has a pre-authentication integer overflow if a client or server is configured to use a crafted XMSS key. This leads to memory corruption and local code execution because of an error in the XMSS key parsing algorithm. NOTE: the XMSS implementation is considered experimental in all released OpenSSH versions, and there is no supported way to enable it when building portable OpenSSH. Openssh 7.8
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
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 7.1
2020-07-24 CVE-2020-15778 ** DISPUTED ** 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
2007-05-21 CVE-2007-2768 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. Hci_management_node, Hci_storage_node, Solidfire, Steelstore_cloud_integrated_storage, Openssh N/A
2019-01-10 CVE-2018-20685 In OpenSSH 7.9, scp.c in the scp client allows remote SSH servers to bypass intended access restrictions via the filename of . or an empty filename. The impact is modifying the permissions of the target directory on the client side. Ubuntu_linux, Debian_linux, Cloud_backup, Element_software, Ontap_select_deploy, Steelstore_cloud_integrated_storage, Storage_automation_store, Openssh, Solaris, Enterprise_linux, Winscp 5.3
2018-08-17 CVE-2018-15473 OpenSSH through 7.7 is prone to a user enumeration vulnerability due to not delaying bailout for an invalid authenticating user until after the packet containing the request has been fully parsed, related to auth2-gss.c, auth2-hostbased.c, and auth2-pubkey.c. Ubuntu_linux, Debian_linux, Aff_baseboard_management_controller, Cloud_backup, Clustered_data_ontap, Cn1610_firmware, Data_ontap, Data_ontap_edge, Fas_baseboard_management_controller, Oncommand_unified_manager, Ontap_select_deploy, Service_processor, Steelstore_cloud_integrated_storage, Storage_replication_adapter, Vasa_provider, Virtual_storage_console, Openssh, Enterprise_linux_desktop, Enterprise_linux_server, Enterprise_linux_workstation 5.3
