Debian Security Advisory DSA-1803-1 security@debian.org
http://www.debian.org/security/ Thijs Kinkhorst
May 20, 2009 http://www.debian.org/security/faq
- ------------------------------------------------------------------------

Package : nsd, nsd3
Vulnerability : buffer overflow
Problem type : remote
Debian-specific: no
CERT advisory : VU#710316
Debian Bug : 529418 529420

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+etch1 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.

Upgrade instructions
- --------------------

wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
will update the internal database
apt-get upgrade
will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
