Description libreoffice 2018-09-11 16:47:58 UTC
When opening a docx,xlsx,pptx file, LibreOffice tries to access my Firefox's certificate store and keychain (as reported by default AppArmor rules provided by Canonical on Ubuntu 18.04)
Said files has no digital signature to check, if it were the case, it would be required to use system's certificate store and/or seahorse's certificate store.

Affected versions are 6.0.3 provided by Canonical and 6.0.6 provided by document foundation launchpad PPA.

There are no visible reasons for LibreOffice to try to read anything from Firefox.

Here are the logs produced by AppArmor when opening such files :

home/Magissia/.mozilla/firefox/mwad0hks.default/cert8.db" pid=19509 comm="soffice.bin" requested_mask="w" denied_mask="w" fsuid=1000 ouid=1000

Steps to Reproduce:
1. Open any docx file created with Microsoft Word 2013 or superior
2. Enjoy invasion of privacy

Actual Results:
LibreOffice tries to read private files that has nothing to do with the document or LibreOffice

Expected Results:
Not reading Firefox's files when opening documents

Reproducible: Always

User Profile Reset: Yes

OpenGL enabled: Yes
