Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 18.10 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in OpenSSH.

Software Description: - openssh: secure shell (SSH) for secure access to remote machines

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.

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 18.10:
openssh-client 1:7.7p1-4ubuntu0.2

Ubuntu 18.04 LTS:
openssh-client 1:7.6p1-4ubuntu0.2

Ubuntu 16.04 LTS:
openssh-client 1:7.2p2-4ubuntu2.7

Ubuntu 14.04 LTS:
openssh-client 1:6.6p1-2ubuntu2.12

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