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
2005-08-23 CVE-2005-2666 SSH, as implemented in OpenSSH before 4.0 and possibly other implementations, stores hostnames, IP addresses, and keys in plaintext in the known_hosts file, which makes it easier for an attacker that has compromised an SSH user's account to generate a list of additional targets that are more likely to have the same password or key. Openssh N/A
2010-12-06 CVE-2010-4478 OpenSSH 5.6 and earlier, when J-PAKE is enabled, does not properly validate the public parameters in the J-PAKE protocol, which allows remote attackers to bypass the need for knowledge of the shared secret, and successfully authenticate, by sending crafted values in each round of the protocol, a related issue to CVE-2010-4252. Openssh N/A
2012-01-27 CVE-2012-0814 The auth_parse_options function in auth-options.c in sshd in OpenSSH before 5.7 provides debug messages containing authorized_keys command options, which allows remote authenticated users to obtain potentially sensitive information by reading these messages, as demonstrated by the shared user account required by Gitolite. NOTE: this can cross privilege boundaries because a user account may intentionally have no shell or filesystem access, and therefore may have no supported way to read an... Openssh N/A
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-2016-10012 The shared memory manager (associated with pre-authentication compression) in sshd in OpenSSH before 7.4 does not ensure that a bounds check is enforced by all compilers, which might allows local users to gain privileges by leveraging access to a sandboxed privilege-separation process, related to the m_zback and m_zlib data structures. Openssh 7.8
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
2019-01-31 CVE-2019-6109 An issue was discovered in OpenSSH 7.9. Due to missing character encoding in the progress display, a malicious server (or Man-in-The-Middle attacker) can employ crafted object names to manipulate the client output, e.g., by using ANSI control codes to hide additional files being transferred. This affects refresh_progress_meter() in progressmeter.c. Ubuntu_linux, Debian_linux, Fedora, M10\-1_firmware, M10\-4_firmware, M10\-4s_firmware, M12\-1_firmware, M12\-2_firmware, M12\-2s_firmware, Element_software, Ontap_select_deploy, Storage_automation_store, Openssh, Enterprise_linux, Enterprise_linux_eus, Enterprise_linux_server_aus, Enterprise_linux_server_tus, Scalance_x204rna_eec_firmware, Scalance_x204rna_firmware, Winscp 6.8
2019-01-31 CVE-2019-6111 An issue was discovered in OpenSSH 7.9. Due to the scp implementation being derived from 1983 rcp, the server chooses which files/directories are sent to the client. However, the scp client only performs cursory validation of the object name returned (only directory traversal attacks are prevented). A malicious scp server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the scp client target directory. If recursive operation (-r) is performed, the server can manipulate... Mina_sshd, Ubuntu_linux, Debian_linux, Fedora, Freebsd, M10\-1_firmware, M10\-4_firmware, M10\-4s_firmware, M12\-1_firmware, M12\-2_firmware, M12\-2s_firmware, Openssh, Enterprise_linux, Enterprise_linux_eus, Enterprise_linux_server_aus, Enterprise_linux_server_tus, Scalance_x204rna_eec_firmware, Scalance_x204rna_firmware, Winscp 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, Communications_offline_mediation_controller, Zfs_storage_appliance 7.1
