More information:

The security update announced as DLA-1025-1 in bind9 introduced a regression.

The fix for CVE-2017-3142 broke verification of TSIG signed TCP message sequences where not all the messages contain TSIG records. This is conform to the spec and may be used in AXFR and IXFR response.

For Debian 7 Wheezy, these problems have been fixed in version 1:9.8.4.dfsg.P1-6+nmu2+deb7u18.

We recommend that you upgrade your bind9 packages.
