    imagemagick vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 16.04 LTS
    - Ubuntu 15.10
    - Ubuntu 14.04 LTS
    - Ubuntu 12.04 LTS
    
    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)
    
    Update instructions:
