    <p>
    PCRE is a Perl-compatible regular expression library. GLib includes a
    copy of PCRE.
    </p>
  </background>
  <description>
    <p>
    PCRE contains a buffer overflow vulnerability when processing a
    character class containing a very large number of characters with
    codepoints greater than 255.
    </p>
  </description>
  <impact type="high">
    <p>
    A remote attacker could exploit this vulnerability by sending a
    specially crafted regular expression to an application making use of
    the PCRE library, which could possibly lead to the execution of
    arbitrary code or a Denial of Service.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All PCRE users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=dev-libs/libpcre-7.6-r1&quot;</code>
    <p>
