The resulting assertion failure causes the name server process to crash, making name resolution unavailable. (CVE-2011-1910)

In addition, this update fixes handling of certain signed/unsigned zone combinations when a DLV service is used. Previously, data from certain affected zones could become unavailable from the resolver.

For the oldstable distribution (lenny), this problem has been fixed in version 1:9.6.ESV.R4+dfsg-0+lenny2.

For the stable distribution (squeeze), this problem has been fixed in version 1:9.7.3.dfsg-1~squeeze2.

The testing distribution (wheezy) and the unstable distribution (sid) will be fixed soon.

We recommend that you upgrade your bind9 packages.");
