Date Id Summary Products Score Patch Annotated
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
2006-09-27 CVE-2006-5051 Signal handler race condition in OpenSSH before 4.4 allows remote attackers to cause a denial of service (crash), and possibly execute arbitrary code if GSSAPI authentication is enabled, via unspecified vectors that lead to a double-free. Mac_os_x, Mac_os_x_server, Debian_linux, Openssh 8.1
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
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
