Yderligere oplysninger:

Przemyslaw Frasunek <venglin@FREEBSD.LUBLIN.PL> rapporterede at ntp-daemoner som den der frigives med Debian GNU/Linux er sårbare med hensyn til buffer-overløb, der kan føre til at udefrakommende kan få root-adgang. En tidligere bulletin (DSA-045-1) rettede delvist dette problem, men introducerede et potentielt overbelastningsangreb ("Denial of Service"). Dette er rettet i Debian 2.2 (potato) i ntp version 4.0.99g-2potato2.
