Details

Micha Krause discovered that Bind did not correctly validate certain
dynamic DNS update packets. An unauthenticated remote attacker could
send specially crafted traffic to crash the DNS server, leading to a
denial of service.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 9.04

• bind9 - 1:9.5.1.dfsg.P2-1ubuntu0.1

Ubuntu 8.10

• bind9 - 1:9.5.0.dfsg.P2-1ubuntu3.2

Ubuntu 8.04

• bind9 - 1:9.4.2.dfsg.P2-2ubuntu0.2

Ubuntu 6.06

• bind9 - 1:9.3.2-2ubuntu1.7

In general, a standard system upgrade is sufficient to effect the
necessary changes.
