VULHUB ™

The Nokia 6210/3310/3330 handsets are prone to denial of service attacks when receiving SMS (Short Message Service) messages that contain malformed User Data Headers (UDH). This condition may allegedly persist as long as the SMS message remains in the user's inbox, rendering the handset useless until the message is removed from the inbox or another SIM card is used with the affected handset. Information from similar vulnerabilities related to malformed SMS messages indicate that the handset may be restored by disconnecting/reconnecting the battery and then rebooting the phone. It is not known if this measure is effective in restoring the phone to normal operating capacity once this vulnerability has been triggered, however, users should consider this measure when attempting to restore their handset. It is not known if other Nokia handsets are affected, or if other vendors produce handsets that are similarly vulnerable.
