Specifically, a hostname with an extensive number of resource records can substantially degrade the performance of bind's resolver cache and authoritative zone databases. This degradation occurs during the addition or updating of these records, and is further exacerbated by client queries, which can lead to resource exhaustion. Consequently, the system may experience increased latency or complete unavailability of DNS services, resulting in a Denial of Service (DoS).\nThe DHCP package as shipped with Red Hat Enterprise 9 is not affected by this vulnerability. Although the DHCP binary ships bundled versions of bind libraries, the DHCP application uses its own routines to DDNS and configuration meaning the affected code is not reachable through it.", "threat_severity": "Important"}
