    Subversion client and server might allow remote attackers to execute

    <p>
    Matt Lewis of Google reported multiple integer overflows in the
    libsvn_delta library, possibly leading to heap-based buffer overflows.
    </p>
  </description>
  <impact type="high">
    <p>
    A remote attacker with commit access could exploit this vulnerability
    by sending a specially crafted commit to a Subversion server, or a
    remote attacker could entice a user to check out or update a repository
    from a malicious Subversion server, possibly resulting in the execution
    of arbitrary code with the privileges of the user running the server or
    client.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Subversion users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=dev-util/subversion-1.6.4"</code>
  </resolution>
