openssh vulnerabilities

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 issus 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.

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

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