    syntax, supporting numerous protocols. libcurl is the corresponding
    client-side library.

  <description>
    <p>
    Ulf Harnhammar reported a possible buffer overflow in the handling
    of TFTP URLs in libcurl due to the lack of boundary checks.
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could exploit this vulnerability to compromise a
    user's system by enticing the user to request a malicious URL with
    cURL/libcurl or to use a HTTP server redirecting to a malicious TFTP
    URL.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All cURL users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=net-misc/curl-7.15.1-r1&quot;</code>
  </resolution>
