Details
USN-6005-1 fixed vulnerabilities in Sudo. This update
provides the corresponding updates for Ubuntu 16.04 LTS.
Original advisory details:
Matthieu Barjole and Victor Cutillas discovered that Sudo incorrectly
escaped control characters in log messages and sudoreplay output. An
attacker could possibly use these issues to inject terminal control
characters that alter output when being viewed.

Ubuntu 16.04
