Technical details
LibreOffice on Linux uses GStreamer to play linked audio and video media. When a document links to an HLS playlist file, GStreamer resolves and reads the local files and remote URLs named within the playlist during document load, with their contents potentially leaked back through the document. The vulnerability is triggered on document open without user interaction beyond the initial document open. Fixed versions prevent LibreOffice from following playlists that reference further resources and place linked media under link update control.
Affected products
- The Document Foundation LibreOffice before 26.2.5 and 26.8.0
