  <description>
    <p>
    Chris Evans (Google Security) reported that the libexslt library that
    is part of libxslt is affected by a heap-based buffer overflow in the
    RC4 encryption/decryption functions.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to process an XML file using a
    specially crafted XSLT stylesheet in an application linked against
    libxslt, possibly leading to the execution of arbitrary code with the
    privileges of the user running the application.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All libxslt users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=dev-libs/libxslt-1.1.24-r1"</code>
