QSN-8696-1: Bind vulnerability
August 31, 2026
Summary
Bind could be made to crash if it received specially crafted network traffic.
Details
It was discovered that Bind incorrectly handled DNSSEC validation when a domain was covered by both NSEC and NSEC3 records with only one type having an RRSIG. A remote attacker could possibly use this issue to cause Bind to crash, resulting in a denial of service.

Internally-facing: only accessible when logged into the QuantaStor console/ssh as the qadmin administrative sudo user; generally lower priority. Externally-facing: part of a service the storage platform presents on the network (or the kernel), so potentially reachable over the network.
