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 DnsResolveContext insufficiently validates the bailiwick of NS records, enabling DNS Cache Poisoning. An attacker controlling an authoritative name...

RUSTSEC-2026-0179 Unbounded SCRAM iteration count allows a malicious server to cause CPU-exhaustion denial of service

A malicious, compromised, or man-in-the-middle server can supply an arbitrarily large SCRAM-SHA-256 PBKDF2 iteration count during authentication. The client runs it inline with no upper bound, pinning a tokio worker thread for minutes per connection, possibly stalling the whole async runtime...

RUSTSEC-2026-0180 Panic decoding a malformed `hstore` value allows denial of service

A malicious or compromised server can return a binary hstore value with an invalid internal length field, causing the client to panic while decoding it. Applications that connect only to a trusted database are not exposed; the risk applies to clients that may connect to untrusted or user-supplied...
