Nokia N70 cell phone allows remote attackers to cause a denial of service (reboot or shutdown) through a wireless Bluetooth connection via a malformed Logical Link Control and Adaptation Protocol (L2CAP) packet whose length field is less than the actual length of the packet, possibly triggering a buffer overflow, as demonstrated using the Bluetooth Stack Smasher (BSS).
