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

crafted document, a remote attacker could exploit this to obtain sensitive
information. (CVE-2018-6871)
