More information:

Ilja van Sprundel discovered that a buffer overflow in NSD, an authoritative name service daemon, allowed to crash the server by sending a crafted packet, creating a denial of service.

For the old stable distribution (etch), this problem has been fixed in version 2.3.6-1+etch4 of the nsd package.

For the stable distribution (lenny), this problem has been fixed in version 2.3.7-1.1+lenny1 of the nsd package and version 3.0.7-3.lenny2 of the nsd3 package.

For the unstable distribution (sid), this problem has been fixed in version 2.3.7-3 for nsd; nsd3 will be fixed soon.

We recommend that you upgrade your nsd or nsd3 package.

Fixed in:

Debian GNU/Linux 4.0 (etch)
