| Doc Text: |
A vulnerability exists in BIND’s DNS resolver logic that makes it overly permissive when accepting resource records (RRs) in responses. Under certain conditions, this flaw allows attackers to inject unsolicited or forged DNS records into the cache. This can be exploited to poison the resolver cache, redirecting clients to malicious domains or unauthorized servers.
