CVE-2016-7074 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:16.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream pdns package and not the pdns package as distributed by Ubuntu.
An issue has been found in PowerDNS before 3.4.11 and 4.0.2, and PowerDNS recursor before 4.0.4, allowing an attacker in position of man-in-the-middle to alter the content of an AXFR because of insufficient validation of TSIG signatures. A missing check that the TSIG record is the last one, leading to the possibility of parsing records that are not covered by the TSIG signature.
