Ubuntu 17.10 : libreoffice regression (USN-3579-2)

Medium Nessus Plugin ID 107087

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

USN-3579-1 fixed a vulnerability in LibreOffice. After upgrading, it was no longer possible for LibreOffice to open documents from certain locations outside of the user's home directory. This update fixes the problem.

We apologize for the inconvenience.

Original advisory details :

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).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected libreoffice-common package.
