Ytterligare information:

Przemyslaw Frasunek <venglin@FREEBSD.LUBLIN.PL> rapporterade att ntp-servrar, såsom den som medföljer Debian GNU/Linux, är sårbara för buffertspill som kan användas för att utifrån få root-behörighet. En tidigare säkerhetsbulletin (DS-045-1) täckte detta problem delvis, men introducerade en möjlig överbelastningsattack. Detta har rättats för Debian 2.2 (potato) i ntp version 4.0.99g-2potato2.
