netty-resolver-dns: Netty DNS resolver: DNS Cache Poisoning via predictable transaction IDs

A flaw was found in Netty's DNS resolver component. This vulnerability arises from the use of a predictable pseudo-random number generator PRNG for DNS transaction IDs and a static User Datagram Protocol UDP source port. This combination significantly reduces the randomness of DNS queries, making...

io.netty/netty-resolver-dns: Netty has Insufficient Bailiwick Validation for NS Records

A flaw was found in Netty's DnsResolveContext. An attacker controlling an authoritative name server for a subdomain can exploit this vulnerability by providing crafted NS records that are insufficiently validated. This allows the attacker to poison the DNS cache for parent domains, bypassing...

netty-resolver-dns: Netty: Information disclosure and data manipulation due to improper CNAME record validation

A flaw was found in Netty's DnsResolveContext. This vulnerability allows a remote attacker to achieve information disclosure or data manipulation by crafting malicious DNS responses. The flaw occurs because the DnsResolveContext fails to validate the origin bailiwick of CNAME records in DNS...

CVE-2026-45673

Netty is a network application framework for development of protocol servers and clients. Prior to versions 4.1.135.Final and 4.2.15.Final, Netty's DNS resolver uses a predictable PRNG for generating DNS transaction IDs and defaults to a static UDP source port. This combination reduces the entrop...
