CVE-2019-14889: Canonical Ubuntu Linux

High severity, CVSS 8.8. EPSS: 3.2% chance of exploitation in the next 30 days.

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.
