libreoffice vulnerability

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

- Ubuntu 17.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS


LibreOffice would allow unintended access to files over the network.

Software Description:
- libreoffice: Office productivity suite


It was discovered that =WEBSERVICE calls in a document could be used to
read arbitrary files. If a user were tricked in to opening a specially
crafted document, a remote attacker could exploit this to obtain sensitive
information. (CVE-2018-6871)

Update instructions:

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

Ubuntu 17.10:
  libreoffice-core                1:5.4.5-0ubuntu0.17.10.1

Ubuntu 14.04 LTS:

all the necessary changes.
