    Synopsis
    ========

    ImageMagick contains an error in boundary checks when handling EXIF
    information, which could lead to arbitrary code execution.

    Background
    ==========

    ImageMagick is a collection of tools to read, write and manipulate
    images in many formats.

    Affected packages
    =================

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 media-gfx/imagemagick < 6.1.3.2 >= 6.1.3.2

    Description
    ===========

    ImageMagick fails to do proper bounds checking when handling image
    files with EXIF information.

    Impact
    ======

    An attacker could use an image file with specially-crafted EXIF
    information to cause arbitrary code execution with the permissions of
    the user running ImageMagick.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All ImageMagick users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=media-gfx/imagemagick-6.1.3.2"
