[原文]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).

Denial of Service
Loss of Availability
Nokia N70 contains a flaw that may allow a remote denial of service. The issue is triggered when specially crafted L2CAP packets are sent via bluetooth to the victim's cell phone, resulting in a "System error" message or a loss of availability for the phone. The issue is caused due to an error in the handling of certain requests in the bluetooth stack.
Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
