RUSTSEC-2026-0347 Buffered application data sent to outer server after ECH rejection

When a server rejects Encrypted Client Hello ECH, the client completes the handshake using the outer ClientHello and authenticates the server against the ECH config's publicname. At the end of that handshake, rustls encrypted and queued any application data buffered via ClientConnection::writer...

DEBIAN-CVE-2026-101338

When a SVCB or HTTPS RR has filled the wire format RDATA up to the brim, another ECH parameter may overwrite the stack, and once beyond the limit, the base64 decoder can write attacker controlled data of unlimited size. Zone files which are written out by NSD itself, such as for zones for which t...
