Samsung Galaxy Phones Android Dialer Lets Remote Users Deny Service
SecurityTracker Alert ID:  1027571
SecurityTracker URL:
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Updated:  Oct 1 2012
Original Entry Date:  Sep 26 2012
Impact:   Denial of service via network
Fix Available:  Yes  Vendor Confirmed:  Yes  Exploit Included:  Yes  

Description:   A vulnerability was reported in Samsung Galaxy phones. A remote user can cause denial of service conditions.

A remote user can send specially crafted data containing Unstructured Supplementary Service Data (USSD) codes that, when loaded by the target user, will cause the codes to be executed on the target user's device. This can be exploited to remotely wipe the target user's device or destroy the SIM card.

The vulnerability resides in the Android dialer.

Android versions 2.3.6 and 4.0.3 are affected on a Samsung Galaxy S II.

The Samsung Galaxy S III is affected on at least some carrier systems.

[Editor's note: The vulnerability resides in the Android dialer. On Samsung devices, the vulnerability can be exploited to destroy the SIM card and also wipe the target device. On other devices, the vulnerability can be exploited to destroy the SIM card, as described in pending Alert ID 1027587.]

Ravi Borgaonkar reported this vulnerability.

Impact:   A remote user can cause the target user's device to be returned to factory-reset conditions.

A remote user can destroy the SIM card on the target device.

Solution:   The vendor has silently issued a fix, included along with their distribution of Android 4.1 and possibly with other versions.

[Editor's note: Whether or not your device is affected may depend on whether your carrier has pushed the appropriate over-the-air update to your device.]
