  <description>
    <p>Two vulnerabilities have been found in gif2png:</p>
    
    <ul>
      <li>A boundary error in gif2png.c could cause a buffer overflow
        (CVE-2010-4694).
      </li>
      <li>The patch for CVE-2009-5018 causes gif2png to truncate GIF pathnames
        (CVE-2010-4695).
      </li>
    </ul>
  </description>
  <impact type="normal">
    <p>A remote attacker could entice a user to open a specially crafted GIF
      file, possibly resulting in execution of arbitrary code, a Denial of
      Service condition, or the creation of PNG files in unintended
      directories.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All gif2png users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=media-gfx/gif2png-2.5.8"
    </code>
