The remote host is missing an update to pdns announced via advisory DSA 771-1. 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: CVE-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. CVE-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. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%20771-1
