FYI, I saw this DSA come in a few days ago:
Debian Security Advisory
DSA-3664-1 pdns -- security update
Date Reported: 10 Sep 2016
Affected Packages: pdns
Security database references:
In the Debian bugtracking system: Bug 830808.
In Mitre's CVE dictionary: CVE-2016-5426, CVE-2016-5427, CVE-2016-6172.
Multiple vulnerabilities have been discovered in pdns, an
authoritative DNS server. The Common Vulnerabilities and Exposures
project identifies the following problems:
CVE-2016-5426 / CVE-2016-5427
Florian Heinz and Martin Kluge reported that the PowerDNS
Authoritative Server accepts queries with a qname's length
larger than 255 bytes and does not properly handle dot inside
labels. A remote, unauthenticated attacker can take advantage of
these flaws to cause abnormal load on the PowerDNS backend by
sending specially crafted DNS queries, potentially leading to a
denial of service.
It was reported that a malicious primary DNS server can crash a
secondary PowerDNS server due to improper restriction of zone
size limits. This update adds a feature to limit AXFR sizes in
response to this flaw.
For the stable distribution (jessie), these problems have been fixed
in version 3.4.1-4+deb8u6.
We recommend that you upgrade your pdns packages.
