Maxim Shudrak and the HP Zero Day Initiative reported a denial of service vulnerability in BIND, a DNS server. A specially crafted query that includes malformed rdata can cause named daemon to terminate with an assertion failure while rejecting the malformed query.

For the oldstable distribution (squeeze), this problem has been fixed in version 1:9.7.3.dfsg-1~squeeze11. For the stable distribution (wheezy), this problem has been fixed in version 1:9.8.4.dfsg.P1-6+nmu2+deb7u1. For the unstable distribution (sid), this problem will be fixed soon. We recommend that you upgrade your bind9 packages.

The Berkeley Internet Name Domain (BIND) implements an Internet domain name server. BIND is the most widely-used name server software on the Internet, and is supported by the Internet Software Consortium, www.isc.org. This package provides the server and related configuration files.
