bluez vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 18.04 LTS


BlueZ could be made to crash or run programs if it received specially
crafted traffic.

Software Description:
- bluez: Bluetooth tools and daemons


Julian Rauchberger discovered that BlueZ incorrectly handled memory when
processing SDP attribute requests. A remote attacker could use this issue
to cause BlueZ to crash, leading to a denial of service, or possibly
execute arbitrary code.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 18.04 LTS:
bluez 5.48-0ubuntu3.7
libbluetooth3 5.48-0ubuntu3.7

In general, a standard system update will make all the necessary changes.
