Ubuntu Security Notice (C) 2016 Canonical, Inc. / NASL script (C) 2016 Tenable Network Security, Inc.


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.
