(Multiple Ralink wireless drivers: Execution of arbitrary code)

    Aviv reported an integer overflow in multiple Ralink wireless card
    drivers when processing a probe request packet with a long SSID,
    possibly related to an integer signedness error.
  
Impact :

    A physically proximate attacker could send specially crafted packets to
    a user who has wireless networking enabled, possibly resulting in the
    execution of arbitrary code with root privileges.
  
Workaround :

    Unload the kernel modules."
