    Package : imagemagick
    CVE ID : CVE-2016-3714 CVE-2016-3715 CVE-2016-3716 CVE-2016-3717
    CVE-2016-3718
    Debian Bug : 823542

    Nikolay Ermishkin from the Mail.Ru Security Team and Stewie discovered
    several vulnerabilities in ImageMagick, a program suite for image
    manipulation. These vulnerabilities, collectively known as ImageTragick,
    are the consequence of lack of sanitization of untrusted input. An
    attacker with control on the image input could, with the privileges of
    the user running the application, execute code (CVE-2016-3714), make HTTP
    GET or FTP requests (CVE-2016-3718), or delete (CVE-2016-3715), move (CVE-2016-3716), or read (CVE-2016-3717) local files.

    These vulnerabilities are particularly critical if Imagemagick processes
    images coming from remote parties, such as part of a web service.

    The update disables the vulnerable coders (EPHEMERAL, URL, MVG, MSL, and
    PLT) and indirect reads via /etc/ImageMagick-6/policy.xml file. In
    addition, we introduce extra preventions, including some sanitization for
    input filenames in http/https delegates, the full remotion of PLT/Gnuplot decoder, and the need of explicit reference in the filename for the
    insecure coders.

    For the stable distribution (jessie), these problems have been fixed in
    version 8:6.8.9.9-5+deb8u2.

    We recommend that you upgrade your imagemagick packages.
