    <p>
    Chris Evans (Google Security) discovered a stack-based buffer overflow
    within the zseticcspace() function in the file zicc.c when processing a
    PostScript file containing a long "Range" array in a .seticcscpate
    operator.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could exploit this vulnerability by enticing a user
    to open a specially crafted PostScript file, which could possibly lead
    to the execution of arbitrary code or a Denial of Service.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Ghostscript ESP users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=app-text/ghostscript-esp-8.15.4-r1"</code>
    <p>
    All Ghostscript GPL users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=app-text/ghostscript-gpl-8.61-r3"</code>
    <p>
    All Ghostscript GNU users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=app-text/ghostscript-gnu-8.60.0-r2"</code>
