This is a highly critical issue, I've described two ways to exploit this on a fully updated Fedora 38 to execute arbitrary commands here: https://bugzilla.redhat.com/show_bug.cgi?id=2241108#c3

Comment 3 Alexander Neumann 2023-10-12 08:49:43 UTC
Just to be clear: opening a LibreOffice document is enough to trigger the RCE: we've made a video here: https://twitter.com/RedTeamPT/status/1712379361146318896

Here's a video which shows the exploit for convert: https://twitter.com/RedTeamPT/status/1712379364136964411

Comment 8 Fedora Blocker Bugs Application 2023-10-13 16:36:19 UTC
Proposed as a Blocker for 39-final by Fedora user thebeanogamer using the blocker tracking app because:

 The release must contain no known security bugs of 'important' or higher impact according to the Red Hat severity classification scale which cannot be satisfactorily resolved by a package update (e.g. issues during installation). 

This impacts Libreoffice and ImageMagick, which can run in a live environment before package updates.
