More information:

Przemyslaw Frasunek <venglin@FREEBSD.LUBLIN.PL> reported that ntp daemons such as that released with Debian GNU/Linux are vulnerable to a buffer overflow that can lead to a remote root exploit. A previous advisory (DSA-045-1) partially addressed this issue, but introduced a potential denial of service attack. This has been corrected for Debian 2.2 (potato) in ntp version 4.0.99g-2potato2.

Fixed in:

Debian 2.2 (potato)
