    libreoffice regression


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

    • Ubuntu 17.10
    Summary


    USN-3579-1 caused a regression in LibreOffice.

    Software Description

    • libreoffice - Office productivity suite
    Details


    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)

    Update instructions


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

    Ubuntu 17.10
    libreoffice-common - 1:5.4.5-0ubuntu0.17.10.5



    To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.

    After a standard system update you need to restart LibreOffice to make all the necessary changes.
