bind: Cache poisoning attacks with unsolicited RRs

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...

bind: Resource exhaustion via malformed DNSKEY handling

A vulnerability was found in BIND 9 resolvers, where processing malformed DNSKEY records from a specially crafted zone can lead to resource exhaustion, primarily causing excessive CPU utilization. This issue enables a remote, unauthenticated attacker to degrade resolver performance and potentiall...

bind: Cache poisoning due to weak PRNG

A vulnerability was found in BIND resolvers caused by a weakness in the Pseudo Random Number Generator PRNG. This weakness allows an attacker to potentially predict the source port and query ID used by BIND, enabling cache poisoning attacks. If successful, the attacker can inject malicious DNS...
