Nel framework multimediale GStreamer, utilizzato in GNOME, sono state scoperte 29 vulnerabilit\u00e0. Otto vulnerabilit\u00e0 portano a scritture di dati al di fuori del buffer e una (CVE-2024-47540) alla sovrascrittura di un puntatore di funzione. Queste vulnerabilit\u00e0 potrebbero essere sfruttate da malintenzionati per eseguire codice durante l'elaborazione di dati multimediali formattati in modo errato nei formati MKV, MP4, Ogg, Vorbis e Opus, cos\u00ec come nei sottotitoli formato SSA. Le altre vulnerabilit\u00e0 comportano dereferenziazioni di puntatori nulli o letture da aree di memoria al di fuori del buffer, quindi possono essere utilizzate per provocare un arresto anomalo. <\/p>\n

La libreria GStreamer \u00e8 utilizzata per analizzare i file multimediali nelle applicazioni Nautilus (GNOME Files), GNOME Videos e Rhythmbox, oltre che nel motore di ricerca tracker-miners sviluppato da GNOME. Questo motore \u00e8 installato in molte distribuzioni come dipendenza del pacchetto tracker-extract, utilizzato in GNOME per analizzare automaticamente i metadati nei nuovi file. Tra l'altro, il servizio indicizza tutti i file nella home directory senza alcuna azione da parte dell'utente. Quindi, per attaccare, \u00e8 sufficiente inserire un file multimediale appositamente creato nella directory dell'utente e la vulnerabilit\u00e0 sar\u00e0 sfruttata durante la sua indicizzazione automatica. <\/p>\n

Le vulnerabilit\u00e0 sono state risolte nell'aggiornamento GStreamer 1.24.10 (pacchetti gst-plugins-good, gst-plugins-base, gstreamer-plugins-ogg, gstreamer-plugins-opus, gstreamer-plugins-vorbis). Oltre alle 29 vulnerabilit\u00e0 identificate dai ricercatori del GitHub Security Lab, nella versione 1.24.10 \u00e8 stata segnalata la correzione di ulteriori 11 vulnerabilit\u00e0. Gli aggiornamenti nelle distribuzioni possono essere monitorati alle seguenti pagine: Debian, Ubuntu, RHEL, SUSE\/openSUSE, Fedora, Arch, FreeBSD. Nella maggior parte delle distribuzioni con GNOME, il componente tracker-miners \u00e8 attivato per impostazione predefinita e viene caricato come dipendenza forte per il file manager Nautilus (GNOME Files). Per disabilitare tracker-miners, \u00e8 possibile utilizzare i seguenti comandi: <\/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
