| VCID-12kz-zuqz-9qgy | libssh: NULL Pointer Dereference in libssh KEX Session ID Calculation |
CVE-2025-8114
|
| VCID-14g6-yzvh-skan | The publickey_from_privatekey function in libssh before 0.5.4, when no algorithm is matched during negotiations, allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a "Client: Diffie-Hellman Key Exchange Init" packet. |
CVE-2013-0176
|
| VCID-18h1-vmsu-7bbf | Multiple vulnerabilities have been discovered in libssh, the worst of which could lead to remote code execution. |
CVE-2021-3634
|
| VCID-19zh-14c7-93a4 | libssh: Invalid return code for chacha20 poly1305 with OpenSSL backend |
CVE-2025-5987
|
| VCID-2gku-dprh-sqdy | Unchecked Return Value A flaw was found in the libssh implements abstract layer for message digest (MD) operations implemented by different supported crypto backends. The return values from these were not properly checked, which could cause low-memory situations failures, NULL dereferences, crashes, or usage of the uninitialized memory as an input for the KDF. In this case, non-matching keys will result in decryption/integrity failures, terminating the connection. |

CVE-2023-2283
|
| VCID-jzn6-bzzf-nugp | 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.
