Denne motor installeres i mange distributioner som en afh\u00e6ngighed af pakken tracker-extract, der anvendes i GNOME til automatisk parsing af metadata i nye filer. Blandt andet indekserer den n\u00e6vnte tjeneste alle filer i hjemmemappen uden brugerens handling. Dermed er det tilstr\u00e6kkeligt at f\u00e5 et specielt oprettet multimediefil til at vises i brugerens mappe, og s\u00e5rbarheden vil blive udnyttet under den automatiske indeksering.      <\/p>\n<p>I de fleste delfin-distributioner med GNOME aktiveres localsearch-komponenterne (tracker-miners) som standard og indl\u00e6ses som en h\u00e5rd afh\u00e6ngighed til filh\u00e5ndtereren Nautilus (GNOME Files). Fra og med GNOME 46 startes localsearch-processen med brug af sandbox-isolering. For at deaktivere metadata-udtr\u00e6k kan filer med regler fjernes fra mappen \/usr\/share\/localsearch3\/extract-rules\/ eller \/usr\/share\/tracker3-miners\/extract-rules\/.          <\/p>\n<p>Sikkerhedss\u00e5r er blevet rettet i opdateringen GStreamer 1.28.1.

begyndt at se p\u00e5 problemet): Debian, Ubuntu, SUSE, RHEL, Gentoo, Arch, Fedora, FreeBSD.<br \/>\n<br \/>Kilde: <a content=\"nofollow\" rel=\"nofollow\"
