Summary

LibreOffice from 26.2 before 26.2.5 on Linux plays linked audio and video files through GStreamer. A linked HLS playlist can make GStreamer read the local files and remote URLs it lists while the document loads, and their contents can end up in the document. A low-privileged local attacker needs a victim to open a crafted document.

Description from the CNA

LibreOffice can link to audio and video files from a document, and on Linux it plays them with GStreamer. A linked media file could be an HLS playlist that made GStreamer read the local files and remote URLs it listed while the document loaded, and their contents could end up in the document. In fixed versions LibreOffice does not follow playlists that name further resources, and linked media is under link update control.
