Package : pdns
CVE ID : CVE-2016-5426 CVE-2016-5427 CVE-2016-6172
Debian Bug : 830808
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.
CVE-2016-6172
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.
