(Note that cryptographic authentication of time servers is often not enabled in the first place.)

For the stable distribution (etch), this problem has been fixed in version 4.2.2.p4+dfsg-2etch1.

For the unstable distribution (sid), this problem has been fixed in version 4.2.4p4+dfsg-8.

The testing distribution (lenny) will be fixed soon.

We recommend that you upgrade your ntp package.");
