pdns - several

Several problems have been discovered in pdns, a versatile nameserver
that can lead to a denial of service. The Common Vulnerabilities and
Exposures project identifies the following problems:

• CAN-2005-2301
  Norbert Sendetzky and Jan de Groot discovered that the LDAP backend
  did not properly escape all queries, allowing it to fail and not
  answer queries anymore.

• CAN-2005-2302
  Wilco Baan discovered that queries from clients without recursion
  permission can temporarily blank out domains to clients with
  recursion permitted. This enables outside users to blank out a
  domain temporarily to normal users.

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

For the stable distribution (sarge) these problems have been fixed in
version 2.9.17-13sarge1.

For the unstable distribution (sid) these problems have been fixed in
version 2.9.18-1.

We recommend that you upgrade your pdns package.
