More information:

NISCC reported that MyDNS, a DNS server using an SQL database for data storage, can be tricked into an infinite loop by a remote attacker and hence cause a denial of service condition.

The old stable distribution (woody) does not contain mydns packages.

For the stable distribution (sarge) this problem has been fixed in version 1.0.0-4sarge1.

For the unstable distribution (sid) this problem has been fixed in version 1.1.0+pre-3.

We recommend that you upgrade your mydns package.

Fixed in:

Debian GNU/Linux 3.1 (sarge)
