Beschreibung: Eine Sicherheitsluecke in CUPS ermoeglicht lokalen Angreifern eine Denial-of-Service-Attacke gegen den Printserver. Das Problem wird dadurch verursacht, dass die CUPS-Implementation des IPP (Internet Printing Protocol) single-threaded ablaeuft. So kann der Angreifer ueber einen unvollstaendigen Request, der keinen Time-out hervorruft, den Ausdruck von anderen Systemen aus blockieren. Ein erfolgreicher Angriff setzt die Erreichbarkeit des Ports 631/tcp voraus.
