Description

USN-2990-1 ImageMagick vulnerability (a.k.a. ImageTragick)

Medium

Vendor

Imagemagick, Canonical Ubuntu

Versions Affected

Canonical Ubuntu 14.04 LTS

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)
