    different protocols.

    <p>
    curl fails to properly check boundaries when handling NTLM
    authentication.
    </p>
  </description>
  <impact type="normal">
    <p>
    With a malicious server an attacker could send a carefully crafted
    NTLM response to a connecting client leading to the execution of
    arbitrary code with the permissions of the user running curl.
    </p>
  </impact>
  <workaround>
    <p>
    Disable NTLM authentication by not using the --anyauth or --ntlm
    options.
    </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-7.13.1&quot;</code>
  </resolution>
