    Synopsis
    ========

    A format string vulnerability in Ettercap could allow a remote attacker
    to execute arbitrary code.

    Background
    ==========

    Ettercap is a suite of tools for content filtering, sniffing and man in
    the middle attacks on a LAN.

    Affected packages
    =================

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 net-analyzer/ettercap < 0.7.3 >= 0.7.3

    Description
    ===========

    The curses_msg function of Ettercap's Ncurses-based user interface
    insecurely implements formatted printing.

    Impact
    ======

    A remote attacker could craft a malicious network flow that would
    result in executing arbitrary code with the rights of the user running
    the Ettercap tool, which is often root.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All Ettercap users should upgrade to the latest available version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=net-analyzer/ettercap-0.7.3"
