CVE-2024-1737 is an uncontrolled resource-consumption vulnerability in BIND 9 resolver caches and authoritative zone databases. Processing becomes inefficient when a DNS name holds a very large number of resource records, irrespective of resource-record type. Adding or updating such records, and handling client queries for the affected name, can substantially degrade database performance. Affected upstream BIND releases include 9.11.0 through 9.11.37, 9.16.0 through 9.16.50, 9.18.0 through 9.18.27, 9.19.0 through 9.19.24, and corresponding supported 9.11, 9.16, and 9.18 subscription branches.
