Ubuntu Security Notice USN-4120-2
September 10, 2019

systemd regression
==========================================================================

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

– Ubuntu 19.04
– Ubuntu 18.04 LTS

Summary:

USN-4120-1 caused a regression in systemd.

Software Description:
– systemd: system and service manager

Details:

USN-4120-1 fixed a vulnerability in systemd. The update included a recent
SRU from the updates pocket that introduced networking problems for some
users. This update fixes the problem.

We apologize for the inconvenience.

Original advisory details:

It was discovered that the systemd-resolved D-Bus interface did not
enforce appropriate access controls. A local unprivileged user could
exploit this to modify a system’s DNS resolver settings.

Update instructions:

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

Ubuntu 19.04:
systemd 240-6ubuntu5.7

Ubuntu 18.04 LTS:
systemd 237-3ubuntu10.29

After a standard system update you need to reboot your computer to make
all the necessary changes.
