    Carsten Lohrke of Gentoo Linux reported that Pngcrush contains a
    vulnerable version of zlib (GLSA 200507-19).
    </p>
  </description>
  <impact type="normal">
    <p>
    By creating a specially crafted data stream, attackers can
    overwrite data structures for applications that use Pngcrush, resulting
    in a Denial of Service and potentially arbitrary code execution.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Pngcrush users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=media-gfx/pngcrush-1.6.2&quot;</code>
