[Secure-testing-team] Bug#823089: Makes USB SDR devices world-read/writable

Package: librtlsdr0
Version: 0.5.3-5
Severity: grave
Tags: security

librtlsdr0 installs udev rules that set the permission bits for
supported devices to 0666.

*** NEVER, EVER DO THIS! ***

All you should do is to set ENV{ID_SOFTWARE_RADIO}=1.  Then udev will
give all local users access to these devices (see the rule at the end
of /lib/udev/rules.d/70-uaccess.rules).

Ben.
