Created libreoffice tracking bugs for this issue: Affects: fedora-all [bug 1769909] External References: https://www.libreoffice.org/about-us/security/advisories/CVE-2019-9854/ An attacker is able to trigger execution of arbitrary python scripts, previously placed at certain locations in the file system, when libreoffice documents are opened and certain actions are performed. However there are several conditions to successful exploitation: 1. The document needs to have macros associated with certain actions like opening the document, mouse over etc. This can be achieved by sending malicious files to users via email etc and social engineering them to open the document. 2. The malicious script needs to exists on the file system to be executed.
