CVE-2016-6173

CVE-2016-6173 is a remote availability issue in NSD affecting versions before 4.1.11. According to NVD, a DNS master server can trigger denial of service on a slave server by sending a zone transfer with unlimited data, leading to /tmp disk consumption and a possible slave server crash. The published CVSS v3 vector rates this as network-reachable, low-complexity, no-authentication, and high availability impact.
