Vulnerability  : several
Problem-Type   : remote
Debian-specific: no
CVE ID         : CAN-2005-2301 CAN-2005-2302
Debian Bug     : 318798

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 discoverd 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.

Debian: New pdns packages fix denial of service

Updated package.

Summary


Norbert Sendetzky and Jan de Groot discoverd 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

For the unstable distribution (sid) these problems have been fixed in
