ubuntu

June 2, 2016

Several security issues were fixed in ImageMagick.

Summary

Several security issues were fixed in ImageMagick.

Software Description:

- imagemagick: Image manipulation programs and library

Details:

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)
