systemd vulnerabilities
==========================================================================

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

- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in systemd.

Software Description:
- systemd: system and service manager

Details:

Karim Hossen & Thomas Imbert and Nelson William Gamazo Sanchez
independently discovered that systemd-resolved incorrectly handled certain
DNS responses. A remote attacker could possibly use this issue to cause
systemd to temporarily stop responding, resulting in a denial of service.
This issue only affected Ubuntu 16.04 LTS. (CVE-2017-15908)

It was discovered that systemd incorrectly handled automounted volumes. A
local attacker could possibly use this issue to cause applications to hang,
resulting in a denial of service. (CVE-2018-1049)

Update instructions:

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

Ubuntu 16.04 LTS:
  systemd                         229-4ubuntu21.1

Ubuntu 14.04 LTS:
  systemd                         204-5ubuntu20.26

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