    <p>Multiple vulnerabilities have been discovered in libarchive. Please
      review the CVE identifiers referenced below for details.
    </p>
  </description>
  <impact type="normal">
    <p>A remote attacker could entice a user or automated process to open a
      specially crafted archive using an application linked against libarchive,
      possibly resulting in execution of arbitrary code with the privileges of
      the process or a Denial of Service condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All libarchive users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=app-arch/libarchive-3.1.2-r1"
    </code>
    
    <p>Packages which depend on this library may need to be recompiled. Tools
      such as revdep-rebuild may assist in identifying some of these packages.
