More information:

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.
