Package : bind9
Vulnerability : improper assert
Problem type : remote
Debian-specific: no
CVE Id(s) : CVE-2009-0696
CERT advisory : VU#725188
Debian Bug : 538975

It was discovered that the BIND DNS server terminates when processing a
specially crafted dynamic DNS update. This vulnerability affects all
BIND servers which serve at least one DNS zone authoritatively, as a
master, even if dynamic updates are not enabled. The default Debian
configuration for resolvers includes several authoritative zones, too,
so resolvers are also affected by this issue unless these zones have
been removed.

For the old stable distribution (etch), this problem has been fixed in
version 9.3.4-2etch5.

For the stable distribution (lenny), this problem has been fixed in
version 9.5.1.dfsg.P3-1.

For the unstable distribution (sid), this problem has been fixed in
version 1:9.6.1.dfsg.P1-1.

We recommend that you upgrade your bind9 packages.

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

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

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

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