Description

This module attempts to gain root privileges by exploiting a Python
code injection vulnerability in blueman versions prior to 2.0.3.

The `org.blueman.Mechanism.EnableNetwork` D-Bus interface exposes the
`set_dhcp_handler` function which uses user input in a call to `eval`,
without sanitization, resulting in arbitrary code execution as root.

This module has been tested successfully with blueman version 1.23
on Debian 8 Jessie (x64).
