USN-4605-2: Blueman update

3 November 2020

A security improvement has been made to blueman.



  • blueman - Graphical bluetooth manager


Vaisha Bernard discovered that blueman did not properly sanitize input on
the d-bus interface to blueman-mechanism. A local attacker could possibly
use this issue to escalate privileges and run arbitrary code or cause a
denial of service. (CVE-2020-15238)

While a previous security update fixed the issue, this update provides
additional improvements by enabling PolicyKit authentication for
privileged commands.

Update instructions

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

Ubuntu 20.10
Ubuntu 20.04

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