    Synopsis
    ========

    A format string vulnerability exists in ImageMagick that may allow an
    attacker to execute arbitrary code.

    Background
    ==========

    ImageMagick is a collection of tools and libraries for manipulating a
    wide variety of image formats.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 media-gfx/imagemagick < 6.2.0.4 >= 6.2.0.4

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

    Tavis Ormandy of the Gentoo Linux Security Audit Team has identified a
    flaw in the handling of filenames by the ImageMagick utilities.

    Impact
    ======

    Successful exploitation may disrupt web applications that depend on
    ImageMagick for image processing, potentially executing arbitrary code.

    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-6.2.0.4"
