blueman vulnerability
==========================================================================

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

– Ubuntu 20.10
– Ubuntu 20.04 LTS

Summary:

A security improvement has been made to blueman.

Software Description:
– blueman: Graphical bluetooth manager

Details:

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:
blueman 2.1.3-2ubuntu1.1

Ubuntu 20.04 LTS:
blueman 2.1.2-1ubuntu0.2

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