| CVE | Vendors | Products | Updated | CVSS v2 | CVSS v3 |
|---|---|---|---|---|---|
| CVE-2020-1730 | 6 Canonical, Fedoraproject, Libssh and 3 more | 6 Ubuntu Linux, Fedora, Libssh and 3 more | 2026-06-17 | 5.0 MEDIUM | 5.3 MEDIUM |
| 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. The server or client could crash when the connection hasn't been fully initialized and the system tries to cleanup the ciphers when closing the connection. The biggest threat from this vulnerability is system availability. | |||||
| CVE-2020-16135 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2026-06-17 | 4.3 MEDIUM | 5.9 MEDIUM |
| libssh 0.9.4 has a NULL pointer dereference in tftpserver.c if ssh_buffer_new returns NULL. | |||||
| CVE-2019-14889 | 6 Canonical, Debian, Fedoraproject and 3 more | 6 Ubuntu Linux, Debian Linux, Fedora and 3 more | 2026-06-17 | 9.3 HIGH | 8.8 HIGH |
| A flaw was found with the libssh API function ssh_scp_new() in versions before 0.9.3 and before 0.8.8. When the libssh SCP client connects to a server, the scp command, which includes a user-provided path, is executed on the server-side. In case the library is used in a way where users can influence the third parameter of the function, it would become possible for an attacker to inject arbitrary commands, leading to a compromise of the remote target. | |||||
| CVE-2018-10933 | 6 Canonical, Debian, Libssh and 3 more | 9 Ubuntu Linux, Debian Linux, Libssh and 6 more | 2026-06-17 | 6.4 MEDIUM | 9.1 CRITICAL |
| A vulnerability was found in libssh's server-side state machine before versions 0.7.6 and 0.8.4. A malicious client could create channels without first performing authentication, resulting in unauthorized access. | |||||
| CVE-2016-0739 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2026-06-17 | 4.3 MEDIUM | 5.9 MEDIUM |
| 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." | |||||
| CVE-2015-3146 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2026-06-17 | 5.0 MEDIUM | 7.5 HIGH |
| The (1) SSH_MSG_NEWKEYS and (2) SSH_MSG_KEXDH_REPLY packet handlers in package_cb.c in libssh before 0.6.5 do not properly validate state, which allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a crafted SSH packet. | |||||
| CVE-2014-8132 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2026-06-17 | 5.0 MEDIUM | N/A |
| Double free vulnerability in the ssh_packet_kexinit function in kex.c in libssh 0.5.x and 0.6.x before 0.6.4 allows remote attackers to cause a denial of service via a crafted kexinit packet. | |||||
| CVE-2014-0017 | 1 Libssh | 1 Libssh | 2026-06-17 | 1.9 LOW | N/A |
| The RAND_bytes function in libssh before 0.6.3, when forking is enabled, does not properly reset the state of the OpenSSL pseudo-random number generator (PRNG), which causes the state to be shared between children processes and allows local users to obtain sensitive information by leveraging a pid collision. | |||||
| CVE-2013-0176 | 1 Libssh | 1 Libssh | 2026-06-16 | 4.3 MEDIUM | N/A |
| 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-2012-6063 | 1 Libssh | 1 Libssh | 2026-06-16 | 7.5 HIGH | N/A |
| Double free vulnerability in the sftp_mkdir function in sftp.c in libssh before 0.5.3 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unspecified vectors, a different vector than CVE-2012-4559. | |||||
| CVE-2012-4562 | 1 Libssh | 1 Libssh | 2026-06-16 | 7.5 HIGH | N/A |
| Multiple integer overflows in libssh before 0.5.3 allow remote attackers to cause a denial of service (infinite loop or crash) and possibly execute arbitrary code via unspecified vectors, which triggers a buffer overflow, infinite loop, or possibly some other unspecified vulnerabilities. | |||||
| CVE-2012-4561 | 1 Libssh | 1 Libssh | 2026-06-16 | 5.0 MEDIUM | N/A |
| The (1) publickey_make_dss, (2) publickey_make_rsa, (3) signature_from_string, (4) ssh_do_sign, and (5) ssh_sign_session_id functions in keys.c in libssh before 0.5.3 free "an invalid pointer on an error path," which might allow remote attackers to cause a denial of service (crash) via unspecified vectors. | |||||
| CVE-2012-4560 | 1 Libssh | 1 Libssh | 2026-06-16 | 7.5 HIGH | N/A |
| Multiple buffer overflows in libssh before 0.5.3 allow remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via unspecified vectors. | |||||
| CVE-2012-4559 | 1 Libssh | 1 Libssh | 2026-06-16 | 6.8 MEDIUM | N/A |
| Multiple double free vulnerabilities in the (1) agent_sign_data function in agent.c, (2) channel_request function in channels.c, (3) ssh_userauth_pubkey function in auth.c, (4) sftp_parse_attr_3 function in sftp.c, and (5) try_publickey_from_file function in keyfiles.c in libssh before 0.5.3 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unspecified vectors. | |||||
