    <p>
    R is a GPL licensed implementation of S, a language and environment for
    statistical computing and graphics. PCRE is a library providing
    functions for Perl-compatible regular expressions.
    </p>
  </background>
  <description>
    <p>
    R includes a copy of PCRE which is vulnerable to multiple buffer
    overflows and memory corruptions vulnerabilities (GLSA 200711-30).
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could entice a user to process specially crafted regular
    expressions with R, which could possibly lead to the execution of
    arbitrary code, a Denial of Service or the disclosure of sensitive
    information.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All R users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=dev-lang/R-2.2.1-r1"</code>
  </resolution>
