The cache could become poisoned with incorrect records leading to queries being made to the wrong servers, which might also result in false information being returned to clients.
A cache poisoning vulnerability was found in BIND when using forwarders. Bogus NS records supplied by the forwarders may be cached and used by name if it needs to recurse for any reason. This issue causes it to obtain and pass on potentially incorrect answers. This flaw allows a remote high privileged attacker to manipulate cache results with incorrect records, leading to queries made to the wrong servers, possibly resulting in false information received on the client's end.
Отчет
Versions of BIND shipped with Red Hat Enterprise Linux 8, 9 are affected, because vulnerable code is present in our code base. For RHEL-9, DHCP uses the vulnerable BIND 9 libraries (bind-9.11.14) for some services. Hence, it is affected as well. Authoritative - Only BIND 9 servers are not vulnerable to this flaw.
Меры по смягчению последствий
If applicable, modify your configuration to either remove all forwarding or all possibility of recursion. Depending on your use case, it may be possible to use other zone types to replace forward zones.
