DSA-771-1 pdns Detailed Explanation for this Vulnerability Assessment 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: Norbert Sendetzky and Jan de Groot discovered that the LDAP backend did not properly escape all queries, permiting it to fail and not answer queries anymore. 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.
