FireEye issued a patch for the flaw, which affects its NX, EX, FX and AX Series appliances. The appliances passively monitor network traffic and pluck out suspicious files for study away from the live network. A successful attack could be triggered merely by sending someone an email or getting the person to click a link, researchers say.”]
