  <description>
    <p>Gentoo Linux developer, Hanno Böck, discovered an off-by-one error in
      the dpkg-deb component of dpkg, the Debian package management system,
      which triggers a stack-based buffer overflow.
    </p>
  </description>
  <impact type="normal">
    <p>An attacker could potentially execute arbitrary code if an user or an
      automated system were tricked into processing a specially crafted Debian
      binary package (.deb).
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All dpkg users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=app-arch/dpkg-1.17.26"
    </code>
