    <p>
    cURL is a command line tool and library for transferring files via
    many different protocols. It supports NTLM authentication to retrieve
    files from Windows-based systems.

    <p>
    iDEFENSE reported that insufficient bounds checking on a memcpy()
    of the supplied NTLM username can result in a stack overflow.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could setup a malicious server and entice an
    user to connect to it using a cURL client, potentially 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 when using cURL (the command line version). Workarounds for
    programs that use the cURL library depend on the configuration options
    presented by those programs.
    </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-7.15.0&quot;</code>
  </resolution>
