CVE-2024-1737: BIND's database will be slow if a very large number of RRs exist at the same name

First published: Fri Jul 19 2024(Updated: )

ISC BIND is vulnerable to a denial of service, caused by an error when content is being added or updated in resolver caches and authoritative zone databases that hold significant numbers of RRs for the same hostname (of any RTYPE). By processing queries, a remote attacker could exploit this vulnerability to cause the database to slow down.
