| CVE-2019-17067 | 2 Microsoft, Putty | 2 Windows, Putty | 2024-08-05 | 9.8 Critical |
| PuTTY before 0.73 on Windows improperly opens port-forwarding listening sockets, which allows attackers to listen on the same port to steal an incoming connection. | ||||
| CVE-2019-17068 | 2 Opensuse, Putty | 2 Leap, Putty | 2024-08-05 | 7.5 High |
| PuTTY before 0.73 mishandles the "bracketed paste mode" protection mechanism, which may allow a session to be affected by malicious clipboard content. | ||||
| CVE-2019-17069 | 3 Netapp, Opensuse, Putty | 3 Oncommand Unified Manager Core Package, Leap, Putty | 2024-08-05 | 7.5 High |
| 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. | ||||
| CVE-2019-9897 | 5 Debian, Fedoraproject, Netapp and 2 more | 5 Debian Linux, Fedora, Oncommand Unified Manager and 2 more | 2024-08-04 | N/A |
| Multiple denial-of-service attacks that can be triggered by writing to the terminal exist in PuTTY versions before 0.71. | ||||
| CVE-2019-9896 | 3 Microsoft, Opensuse, Putty | 4 Windows, Backports Sle, Leap and 1 more | 2024-08-04 | 7.8 High |
| In PuTTY versions before 0.71 on Windows, local attackers could hijack the application by putting a malicious help file in the same directory as the executable. | ||||
| CVE-2019-9898 | 5 Debian, Fedoraproject, Netapp and 2 more | 5 Debian Linux, Fedora, Oncommand Unified Manager and 2 more | 2024-08-04 | N/A |
| Potential recycling of random numbers used in cryptography exists within PuTTY before 0.71. | ||||
| CVE-2019-9894 | 5 Debian, Fedoraproject, Netapp and 2 more | 5 Debian Linux, Fedora, Oncommand Unified Manager and 2 more | 2024-08-04 | N/A |
| A remotely triggerable memory overwrite in RSA key exchange in PuTTY before 0.71 can occur before host key verification. | ||||
| CVE-2019-9895 | 3 Fedoraproject, Opengroup, Putty | 3 Fedora, Unix, Putty | 2024-08-04 | N/A |
| In PuTTY versions before 0.71 on Unix, a remotely triggerable buffer overflow exists in any kind of server-to-client forwarding. | ||||
| CVE-2020-14002 | 3 Fedoraproject, Netapp, Putty | 3 Fedora, Oncommand Unified Manager Core Package, Putty | 2024-08-04 | 5.9 Medium |
| 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). | ||||
| CVE-2021-36367 | 1 Putty | 1 Putty | 2024-08-04 | 8.1 High |
| 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). | ||||
| CVE-2021-33500 | 2 Microsoft, Putty | 2 Windows, Putty | 2024-08-03 | 7.5 High |
| PuTTY before 0.75 on Windows allows remote servers to cause a denial of service (Windows GUI hang) by telling the PuTTY window to change its title repeatedly at high speed, which results in many SetWindowTextA or SetWindowTextW calls. NOTE: the same attack methodology may affect some OS-level GUIs on Linux or other platforms for similar reasons. | ||||
| CVE-2023-48795 | 43 9bis, Apache, Apple and 40 more | 78 Kitty, Sshd, Sshj and 75 more | 2024-08-02 | 5.9 Medium |
| 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 the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms.
