Other devices based on the same (or earlier) platform are likely to be vulnerable.
In case the handset hangs, battery removal is needed in order to restore normal functionalities.
By sending multiple malformed packet via SMS, an attacker may be able to reboot the handset multiple times, effectively performing an extended denial of service.
The attack can also be performed over an IP bearer using UDP port 2948.
In this case a single malformed broadcast packet can be used to attack and disable a large number of devices, leading to a much heavier impact.
Mobile Security Lab is aware that the problem has been identified: some models, more recent than the ones listed in this advisory, have been found not to be vulnerable.
Further details are not currently available to Mobile Security Lab.
