Im Multimedia-Framework GStreamer, das in GNOME verwendet wird, wurden 29 Sicherheitsanf\u00e4lligkeiten entdeckt. Acht dieser Anf\u00e4lligkeiten f\u00fchren zu einem Buffer-Overflow, und eine (CVE-2024-47540) erm\u00f6glicht das \u00dcberschreiben eines Funktionszeigers. Diese Anf\u00e4lligkeiten k\u00f6nnen potenziell von Angreifern ausgenutzt werden, um die Ausf\u00fchrung von Code bei der Verarbeitung von fehlerhaft formatierten Multimedia-Daten in den Formaten MKV, MP4, Ogg, Vorbis und Opus sowie von Untertiteln im SSA-Format zu initiieren. Die anderen Anf\u00e4lligkeiten f\u00fchren zu Nullzeiger-Dereferenzen oder dem Lesen aus dem Speicher au\u00dferhalb des Puffers und k\u00f6nnen genutzt werden, um einen Absturz auszul\u00f6sen. <\/p>\n

Die GStreamer-Bibliothek wird zur Analyse von Multimedia-Dateien in den Anwendungen Nautilus (GNOME Files), GNOME Videos und Rhythmbox sowie im von GNOME entwickelten Such-Engine-Projekt tracker-miners eingesetzt. Diese Engine wird in vielen Distributionen als Abh\u00e4ngigkeit zum Paket tracker-extract installiert, das in GNOME zur automatischen Analyse von Metadaten in neuen Dateien verwendet wird. Unter anderem indexiert dieser Dienst alle Dateien im Home-Verzeichnis ohne Benutzereingriff. Daher reicht es aus, dass eine speziell erstellte Multimedia-Datei im Benutzerverzeichnis erscheint, um die Anf\u00e4lligkeit w\u00e4hrend der automatischen Indizierung auszunutzen. <\/p>\n

Die Sicherheitsanf\u00e4lligkeiten wurden im Update GStreamer 1.24.10 (Pakete gst-plugins-good, gst-plugins-base, gstreamer-plugins-ogg, gstreamer-plugins-opus, gstreamer-plugins-vorbis) behoben. Neben den 29 Anf\u00e4lligkeiten, die von Forschern des GitHub Security Lab entdeckt wurden, wurden in Version 1.24.10 auch 11 weitere Anf\u00e4lligkeiten behoben. Updates in den Distributionen k\u00f6nnen auf den folgenden Seiten verfolgt werden: Debian, Ubuntu, RHEL, SUSE\/openSUSE, Fedora, Arch, FreeBSD. In den meisten Distributionen mit GNOME wird die Komponente tracker-miners standardm\u00e4\u00dfig aktiviert und als harte Abh\u00e4ngigkeit zum Dateimanager Nautilus (GNOME Files) geladen. Um tracker-miners zu deaktivieren, k\u00f6nnen die folgenden Befehle verwendet werden: <\/p>\n

systemctl --user mask tracker-store.service tracker-miner-fs.service tracker-miner-rss.service tracker-extract.service tracker-miner-apps.service tracker-writeback.service tracker reset --hard
