CVE-2020-1730 6 Canonical, Fedoraproject, Libssh and 3 more 7 Ubuntu Linux, Fedora, Libssh and 4 more 2024-11-21 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 6 Canonical, Debian, Fedoraproject and 3 more 7 Ubuntu Linux, Debian Linux, Fedora and 4 more 2024-11-21 5.9 Medium
libssh 0.9.4 has a NULL pointer dereference in tftpserver.c if ssh_buffer_new returns NULL.
CVE-2019-14889 7 Canonical, Debian, Fedoraproject and 4 more 7 Ubuntu Linux, Debian Linux, Fedora and 4 more 2024-11-21 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 10 Ubuntu Linux, Debian Linux, Libssh and 7 more 2024-11-21 N/A
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.
