@mk the article also quotes: '"A lot of wireless routers shell out to ping and traceroute – these are all likely vulnerable."' (Robert Graham of Errata Security) but I think a lot of routers will use an embedded system like Busybox (which uses Ash) so these will *not* be vulnerable #security (so what does my FRITZ!box run? don't know how to find out...)
