sanitized untrusted input. A remote attacker could use these issues to
execute arbitrary code. These issues are known as 'ImageTragick'. This
update disables problematic coders via the
/etc/ImageMagick-6/policy.xml configuration file. In certain
environments the coders may need to be manually re-enabled after
making sure that ImageMagick does not process untrusted input.
(CVE-2016-3714, CVE-2016-3715, CVE-2016-3716, CVE-2016-3717,
CVE-2016-3718)

Bob Friesenhahn discovered that ImageMagick allowed injecting commands
via an image file or filename. A remote attacker could use this issue
to execute arbitrary code. (CVE-2016-5118).

description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
