VCID-24cg-zw49-b3ab
Aliases: CVE-2024-31497 |
Multiple vulnerabilities have been discovered in PuTTY, the worst of which could lead to compromised keys. |
Affected by 0 other vulnerabilities. |

VCID-5524-rbbb-xydc
Aliases: 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). |
Affected by 0 other vulnerabilities. |

VCID-9ss1-k3at-nub5
Aliases: 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. |
Affected by 0 other vulnerabilities. |

VCID-gp2g-u84g-q7c2
Aliases: 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). |
Affected by 0 other vulnerabilities. |

Aliases: CVE-2023-48795 GHSA-45x7-px36-x8w8 |
Improper Validation of Integrity Check Value 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.
