Sony Ericsson phones vulnerable to attacks

Switch off your Bluetooth

If you use a Sony Ericsson mobile phone, you may want to disable the Bluetooth function. The FrSIRT (French Security Incident Response Team) has warned that a security vulnerability potentially puts some of the company's phones at risk of a DoS (denial-of-service) attack.

The vulnerability is said to affect at least four Sony Ericsson models: the K600i, V600i, W800i and T68i. The flaw is the result of an error in the Bluetooth function, according to an advisory posted on the group's website. L2CAP (Logical Link Control and Adaptation Layer Protocol) packets containing certain headers "could be exploited by remote attackers to cause a denial of service", it said.

However, Sony Ericsson users don't need to lose much sleep over the vulnerability, which FrSIRT has classified as low-risk. The group advises users to turn off the Bluetooth functions in their phones as a solution to the problem.

Sony Ericsson officials were not immediately available to comment.
