Details:

USN-3885-1 fixed vulnerabilities in OpenSSH. It was discovered that the fix for CVE-2019-6111 turned out to be incomplete. This update fixes the problem.

Original advisory details:

Harry Sintonen discovered multiple issues in the OpenSSH scp utility. If a
user or automated system were tricked into connecting to an untrusted
server, a remote attacker could possibly use these issues to write to
arbitrary files, change directory permissions, and spoof client output.

Ubuntu 18.10:
openssh-client 1:7.7p1-4ubuntu0.3

Ubuntu 18.04 LTS:
openssh-client 1:7.6p1-4ubuntu0.3

Ubuntu 16.04 LTS:
openssh-client 1:7.2p2-4ubuntu2.8

Ubuntu 14.04 LTS:
openssh-client 1:6.6p1-2ubuntu2.13

In general, a standard system update will make all the necessary changes.
