DATE CVE VULNERABILITY TITLE RISK
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.
5.9
2019-01-31 CVE-2019-6111 Path Traversal vulnerability in multiple products
An issue was discovered in OpenSSH 7.9.
5.9
2019-01-31 CVE-2019-6110 Inappropriate Encoding for Output Context vulnerability in multiple products
In OpenSSH 7.9, due to accepting and displaying arbitrary stderr output from the server, a malicious server (or Man-in-The-Middle attacker) can manipulate the client output, for example to use ANSI control codes to hide additional files being transferred.

2019-01-31 CVE-2019-6109 Improper Encoding or Escaping of Output vulnerability in multiple products
An issue was discovered in OpenSSH 7.9.
6.8
2019-01-10 CVE-2018-20685 Incorrect Authorization vulnerability in multiple products
In OpenSSH 7.9, scp.c in the scp client allows remote SSH servers to bypass intended access restrictions via the filename of .
5.3
2019-01-10 CVE-2018-20684 Improper Input Validation vulnerability in Winscp
In WinSCP before 5.14 beta, due to missing validation, the scp implementation would accept arbitrary files sent by the server, potentially overwriting unrelated files.

6.4
2014-04-22 CVE-2014-2735 Improper Input Validation vulnerability in Winscp
WinSCP before 5.5.3, when FTP with TLS is used, does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.

5.8
2013-08-19 CVE-2013-4852 Numeric Errors vulnerability in multiple products
Integer overflow in PuTTY 0.62 and earlier, WinSCP before 5.1.6, and other products that use PuTTY allows remote SSH servers to cause a denial of service (crash) and possibly execute arbitrary code in certain applications that use PuTTY via a negative size value in an RSA key signature during the SSH handshake, which triggers a heap-based buffer overflow.
