Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Nikolay Ermishkin and Stewie discovered that ImageMagick incorrectly 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).

Note that Tenable Network Security has extracted the preceding 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.
