For such cases, a registry-based workaround is available that also requires restarting the DNS service. This could cause an unanticipated failure. Therefore,it is possible that some queries mightnot be answered. Privacy Program
However, the registry modification will no longer be needed after the update is applied. Mar 16, 2022Knowledge Summary: On March 16th, 2022 ISC announced a new security issue encountered in BIND 9.18.0 as CVE-2022-0667. Infoblox has been diligently investigating this new threat, and we have concluded that our SaaS products are not subject to this vulnerability at this time. CISA's BOD 22-01 and Known Exploited Vulnerabilities Catalog for further guidance and requirements. The DNS resolver in unspecified versions of Infoblox DNS One, when resolving recursive DNS queries for arbitrary hosts, allows remote attackers to conduct DNS cache poisoning via a birthday attack that uses a large number of open queries for the same resource record (RR) combined with spoofed responses, which increases the possibility of successfully spoofing a response in a way that is more efficient than brute force methods. Find out what's happening in global Ansible Meetups and find one near you. A hotfix has been developed and is available to customers on the Infoblox Support portal. This workaround applies FF00 as the value which has a decimal value of 65280. A vulnerability in the web UI of Cisco Umbrella could allow an unauthenticated, remote attacker to negatively affect the performance of this service. The second task Changing registry settings for DNS parameters makes a change to the registry to restrict the size of the largest inbound TCP-based DNS response packet that's allowed.
Several other nameservers are also known to behave similarly and the reporters are coordinating a response among multiple vendors. The mitigation can be performed by editing the Windows registry and restarting the DNS service. Any use of this information is at the user's risk.
