| 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 |
| 2023-07-21 | CVE-2023-3603 | NULL Pointer Dereference vulnerability in Libssh A missing allocation check in sftp server processing read requests may cause a NULL dereference on low-memory conditions. | 6.5 |
| 2023-05-26 | CVE-2023-1667 | NULL Pointer Dereference vulnerability in multiple products A NULL pointer dereference was found In libssh during re-keying with algorithm guessing. | 6.5 |

| 2021-08-31 | CVE-2021-3634 | Out-of-bounds Write vulnerability in multiple products A flaw has been found in libssh in versions prior to 0.9.6. | 6.5 |
| 2020-07-29 | CVE-2020-16135 | NULL Pointer Dereference vulnerability in multiple products libssh 0.9.4 has a NULL pointer dereference in tftpserver.c if ssh_buffer_new returns NULL. | 5.9 |
| 2020-04-13 | CVE-2020-1730 | NULL Pointer Dereference vulnerability in multiple products A flaw was found in libssh versions before 0.8.9 and before 0.9.4 in the way it handled AES-CTR (or DES ciphers if enabled) ciphers. | 5.3 |
| 2016-04-13 | CVE-2016-0739 | Information Exposure vulnerability in multiple products libssh before 0.7.3 improperly truncates ephemeral secrets generated for the (1) diffie-hellman-group1 and (2) diffie-hellman-group14 key exchange methods to 128 bits, which makes it easier for man-in-the-middle attackers to decrypt or intercept SSH sessions via unspecified vectors, aka a "bits/bytes confusion bug." | 5.9 |
