    <package name="dev-libs/libpcre" auto="yes" arch="*">

  <background>
    <p>
    libpcre is a library providing functions for Perl-compatible
    regular expressions.
    </p>
  </background>
  <description>
    <p>
    libpcre fails to check certain quantifier values in regular
    expressions for sane values.
    </p>
  </description>
  <impact type="high">
    <p>
    An attacker could possibly exploit this vulnerability to execute
    arbitrary code by sending specially crafted regular expressions to
    applications making use of the libpcre library.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All libpcre users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=dev-libs/libpcre-6.3"</code>
  </resolution>
