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... | Kitty, Sshd, Sshj, Macos, Asyncssh, Ssh_client, Ssh_server, Sshlib, Thrussh, Crushftp, Debian_linux, Dropbear_ssh, Erlang\/otp, Fedora, Filezilla_client, Freebsd, Security, Crypto, Maverick_synergy_java_ssh_api, Lanconfig, Lcos, Lcos_fx, Lcos_lx, Lcos_sx, Libssh, Libssh2, Jsch, Powershell, Net\-Ssh, Pfsense_ce, Pfsense_plus, Xshell_7, Openssh, Cyclone_ssh, Nova, Transmit_5, Paramiko, Proftpd, Putty, Advanced_cluster_security, Ceph_storage, Cert\-Manager_operator_for_red_hat_openshift, Discovery, Enterprise_linux, Jboss_enterprise_application_platform, Keycloak, Openshift_api_for_data_protection, Openshift_container_platform, Openshift_data_foundation, Openshift_dev_spaces, Openshift_developer_tools_and_services, Openshift_gitops, Openshift_pipelines, Openshift_serverless, Openshift_virtualization, Openstack_platform, Single_sign\-On, Storage, Pkixssh, Russh, Sftpgo, Ssh, Ssh2, Tera_term, Sftp_gateway_firmware, Tinyssh, Ssh2, Securecrt, Winscp | 5.9 | ||
2019-10-01 | CVE-2019-17069 | PuTTY before 0.73 might allow remote SSH-1 servers to cause a denial of service by accessing freed memory locations via an SSH1_MSG_DISCONNECT message. | Oncommand_unified_manager_core_package, Leap, Putty | 7.5 | ||
2020-06-29 | CVE-2020-14002 | PuTTY 0.68 through 0.73 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). | Fedora, Oncommand_unified_manager_core_package, Putty | 5.9 | ||
2021-07-09 | CVE-2021-36367 | PuTTY through 0.75 proceeds with establishing an SSH session even if it has never sent a substantive authentication response. This makes it easier for an attacker-controlled SSH server to present a later spoofed authentication prompt (that the attacker can use to capture credential data, and use that data for purposes that are undesired by the client user). | Putty | 8.1 | ||
2017-03-27 | CVE-2017-6542 | The ssh_agent_channel_data function in PuTTY before 0.68 allows remote attackers to have unspecified impact via a large length value in an agent protocol message and leveraging the ability to connect to the Unix-domain socket representing the forwarded agent connection, which trigger a buffer overflow. | Leap, Leap, Putty | 9.8 | ||
2019-03-21 | CVE-2019-9894 | A remotely triggerable memory overwrite in RSA key exchange in PuTTY before 0.71 can occur before host key verification. | Debian_linux, Fedora, Oncommand_unified_manager, Leap, Putty | 7.5 | ||
2019-03-21 | CVE-2019-9895 | In PuTTY versions before 0.71 on Unix, a remotely triggerable buffer overflow exists in any kind of server-to-client forwarding. | Fedora, Putty | 9.8 |
