ofono: fix CVE-2023-4233
A flaw was found in ofono, an Open Source Telephony on Linux. A stack overflow bug
is triggered within the sms_decode_address_field() function during the SMS
PDU decoding. It is assumed that the attack scenario is accessible from a compromised
modem, a malicious base station, or just SMS.
