CVE-2016-2120 (CCN-152581)

Assigned:2016-01-29
Published:2018-10-31
Updated:2019-10-09
Summary:An issue has been found in PowerDNS Authoritative Server versions up to and including 3.4.10, 4.0.1 allowing an authorized user to crash the server by inserting a specially crafted record in a zone under their control then sending a DNS query for that record. The issue is due to an integer overflow when checking if the content of the record matches the expected size, allowing an attacker to cause a read past the buffer boundary.
