| 2024-04-15 | CVE-2024-31497 | Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) vulnerability in multiple products In PuTTY 0.68 through 0.80 before 0.81, biased ECDSA nonce generation allows an attacker to recover a user's NIST P-521 secret key via a quick attack in approximately 60 signatures. | 5.9 |
| 2023-12-18 | CVE-2023-48795 | Improper Validation of Integrity Check Value vulnerability in multiple products 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. network high complexity openbsd putty filezilla-project microsoft panic roumenpetrov winscp bitvise lancom-systems vandyke libssh net-ssh ssh2-project proftpd freebsd crates tera-term-project oryx-embedded crushftp netsarang paramiko redhat golang russh-project sftpgo-project erlang matez libssh2 asyncssh-project dropbear-ssh-project jadaptive ssh thorntech netgate connectbot apache tinyssh trilead 9bis gentoo fedoraproject debian apple CWE-354 | 5.9 |
| 2021-07-09 | CVE-2021-36367 | Insufficient Verification of Data Authenticity vulnerability in Putty PuTTY through 0.75 proceeds with establishing an SSH session even if it has never sent a substantive authentication response. | 8.1 |
| 2021-05-21 | CVE-2021-33500 | Unspecified vulnerability in Putty 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. | 7.5 |
| 2020-06-29 | CVE-2020-14002 | Information Exposure Through Discrepancy vulnerability in multiple products PuTTY 0.68 through 0.73 has an Observable Discrepancy leading to an information leak in the algorithm negotiation. | 5.9 |
