Are our WiFI routers and rooftop radios affected by the BashShellshock vulnerability?

    Depends on what one will accept as an "embedded" system;
    the SheevaPlug definitely qualifies as embedded.

    My Sheevaplug servers are fist-sized and the GuruPlug runs
    Debian. Quick example (noting the short uptime is due to
    having had to replace a UPS battery recently) noting that
    root is the only login on such servers:

    Note the sizes of the SheevaPlugs and GuruPlug which have been running
    here since 2009:

    These consume only 4 to 5 Watts power per a Kill-A-Watt device
    and they have GiGE ports to serve my LAN (DHCP, DNS, and more)
    which is all gigabit:

    No it doesn't. It qualifies as a headless server. An embedded system
    is embedded in another machine such as a car or a radio.

    OK, I'll accept that, and this confirms it:

    Thanks! Learn something new every day. :)
