    <p>
    Tavis Ormandy and Will Drewry from the Google Security Team reported a
    failed assertion in file regex/v4/perl_matcher_non_recursive.hpp
    (CVE-2008-0171) and a NULL pointer dereference in function
    get_repeat_type() file basic_regex_creator.hpp (CVE-2008-0172) when
    processing regular expressions.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could provide specially crafted regular expressions
    to an application using Boost, resulting in a crash.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Boost users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=dev-libs/boost-1.34.1-r2&quot;</code>
  </resolution>
