Prior to versions 4.1.135.Final and 4.2.15.Final, Netty&#39;s DNS resolver uses a predictable PRNG for generating DNS transaction IDs and defaults to a static UDP source port. This combination reduces the entropy of DNS queries, enabling DNS Cache Poisoning (Kaminsky attack). Versions 4.1.135.Final and 4.2.15.Final patch the issue.</p> <p>Netty is a network application framework for development of protocol servers and clients.

This combination reduces the entropy of DNS queries, enabling DNS Cache Poisoning (Kaminsky attack).</p> <p>### Details Two factors contribute to this vulnerability in io.netty.resolver.dns: - Predictable Query IDs: `DnsQueryIdSpace` manages 16-bit transaction IDs in buckets of 16,384 IDs. It initializes only the first bucket. When an ID is returned, it is pushed back into the bucket at a random index generated by java.util.concurrent.ThreadLocalRandom:</p> <p>```java Random random = ThreadLocalRandom.current(); int insertionPosition = random.nextInt(count + 1); ```</p> <p>Because ThreadLocalRandom is a predictable LCG and the resolver operates within a single bucket, the sequence of IDs is predictable once the PRNG state is mathematically recovered.</p> <p>- Default Static Source Port: `DnsNameResolverBuilder` defaults to a `channelStrategy` of `ChannelPerResolver`. This binds the DatagramChannel once, resulting in a static source port for all subsequent queries.</p> <p>Combined, a static source port and predictable transaction IDs reduces the entropy required to secure DNS resolution against spoofing.</p> <p>### Impact DNS Cache Poisoning. Downstream applications using the default Netty DNS resolver may connect to malicious IPs, leading to traffic interception or MitM attacks.</p> <p><strong>Affected:</strong> Maven: io.netty:netty-resolver-dns</p> <p>### Summary Netty&#39;s DNS resolver uses a predictable PRNG for generating DNS transaction IDs and defaults to a static UDP source port.
