This vulnerability allows physically present attackers to execute arbitrary code on affected installations of Alpine iLX-F511 devices. Authentication is not required to exploit this vulnerability.\n\nThe specific flaw exists within the handling of Bluetooth OBEX packets. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-29012.","summary":"A heap buffer overflow in how the Alpine iLX-F511 head unit parses Bluetooth OBEX packets lets an attacker copy oversized data into memory.
