Nexus-phones can be made to reboot using the SMS-attack

PCWorld reports that the latest Nexus smartphones can force reboot hang or lose connection to the network due to a problem processing a certain type of SMS. Safety Specialist Alec Bogdan, reportedly found that smartphone Galaxy Nexus, Nexus 4 and Nexus 5 contain a vulnerability that allows attackers to prevent the use of the machine.

By sending your smartphone about 30 Instant Messaging (Flash SMS), immediately displayed on the screen and the machine requires the user actions, the attacker can deduce smartphone failure - the device can lose internet connection or reboot, if not sooner SMS rejected. The problem also lies in the fact that the Nexus-phones do not report incoming Flash SMS by sound, allowing an attacker to send a whole sequence of messages to the user notices.

Bogdan Alec notes that the problem affects devices Nexus, running Android versions of Ice Cream Sandwich to KitKat, but on the other 20 tested Android-smartphones reproduce it failed. Expert notes that reported this problem to Google, and although they assured that a patch will be released along with Android 4.3, the vulnerability is still present. Of course, the average user does not send mass Flash SMS, but it is quite possible with the help of special applications. Its not yet been discovered the deeper flaws that could be caused by the said problem (for example, the possibility of execution of malicious code), but Mr. Alec convinced that this is a serious security hole that Google needs to fix. Google unveiled last reference the Nexus 5 together with the platform Android 4.4 KitKat in late October at an event in San Francisco, the search giant LG has improved with all the key characteristics: it has received a new processor, screen, camera, battery and so on.
