  <description>
    <p>
    M. Joonas Pihlaja has reported that a boundary error exists within the
    ReadDCMImage() function of coders/dcm.c, causing the improper handling
    of DCM images. Pihlaja also reported that there are several boundary
    errors in the ReadPALMImage() function of coders/palm.c, similarly
    causing the improper handling of PALM images.

  <impact type="normal">
    <p>
    An attacker could entice a user to open a specially crafted DCM or PALM
    image with GraphicsMagick, and possibly execute arbitrary code with the
    privileges of the user running GraphicsMagick.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All GraphicsMagick users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=media-gfx/graphicsmagick-1.1.7-r3&quot;</code>
