# Alpine iLX-F511 car head unit: Android Auto handler overflow allows root code execution

The Alpine iLX-F511 head unit's Android Auto connection handler copies attacker-supplied data into a fixed-size stack buffer without checking its length. An attacker who is physically present can run arbitrary code as root on the device.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

Alpine iLX-F511 Android Auto Connection Handler Stack-based Buffer Overflow Remote Code Execution Vulnerability. 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.

The specific flaw exists within the Android Auto connection handler. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-29016.
