What it is about
LibreOffice ist eine leistungsfähige Office-Suite, voll kompatibel mit den Programmen anderer großer Office-Anbieter, für verbreitete Betriebssysteme wie Windows, GNU/Linux und Apple Mac OS X geeignet. LibreOffice bietet sechs Anwendungen für die Erstellung von Dokumenten und zur Datenverarbeitung: Writer, Calc, Impress, Draw, Base und Math. Ein entfernter, anonymer Angreifer kann eine Schwachstelle in LibreOffice ausnutzen, um Dateien zu erzeugen.
