Pierre Betouin has discovered a vulnerability in various Sony Ericsson cell phones, which can be exploited by malicious people to cause a DoS (Denial of Service).

The vulnerability is caused due to an error in the L2CAP (Logical Link Control and Adaptation Layer Protocol) layer. This can be exploited to temporary halt a vulnerable cell phone by sending a L2CAP packet with a specially crafted header through a wireless Bluetooth connection.

Successful exploitation requires that Bluetooth is enabled on the affected device.

The vulnerability has been confirmed to affect Sony Ericsson W800i and has also been reported to affect the following products:
* Sony Ericsson K600i
* Sony Ericsson V600i
* Sony Ericsson T68i

Solution
Disable Bluetooth.
