Produktbeschreibung: CUPS (Common Unix Printing System) ist ein Printspooler, der es lokalen und entfernten Benutzern ermöglicht, Druckfunktionen über das Internet Printing Protocol (IPP) zu nutzen. Red Hat Enterprise Linux (RHEL) ist eine populäre Linux-Distribution. Fedora ist eine von Red Hat abstammende Linux-Distribution.
Angriff: Ein lokaler Angreifer kann eine Schwachstelle in CUPS, wie es z.B. in Red Hat Enterprise Linux und Fedora Linux verwendet wird, ausnutzen, um seine Privilegien zu erhöhen.
