A flaw was found in ofono, an Open Source Telephony on Linux. A stack
overflow bug is triggered within the decode_submit_report() function during
the SMS decoding. It is assumed that the attack scenario is accessible from
a compromised modem, a malicious base station, or just SMS. There is a
bound check for this memcpy length in decode_submit(), but it was forgotten
in decode_submit_report().
