EUVD-2026-318202

fkie_cve-2026-42582

Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final, when decoding header blocks, the non-Huffman branch of io.netty.handler.codec.http3.QpackDecoder#decodeHuffmanEncodedLiteral may execute new byte[length] for a string literal before verifying that length bytes are actually present in the compressed field section. The wire encoding allows a very large length to be expressed in few bytes. There is no check that length <= in.readableBytes() before new byte[length]. This vulnerability is fixed in 4.2.13.Final.

GHSA-2c5c-chwr-9hqw — Netty HTTP/3 QPACK literal unbounded allocation

Affected: Maven: io.netty:netty-codec-http3

### Summary When Netty decodes HTTP/3 headers, it sometimes runs `new byte[length]` using a length from the wire before checking that many bytes are really there. A small malicious header can claim a huge length (on the order of a gigabyte).

### Details When decoding header blocks, the non-Huffman branch of `io.netty.handler.codec.http3.QpackDecoder#decodeHuffmanEncodedLiteral` may execute `new byte[length]` for a string literal before verifying that length bytes are actually present in the compressed field section. The wire encoding allows a very large length to be expressed in few bytes. There is no check that `length <= in.readableBytes()` before `new byte[length]`.

### PoC The test below constructs a small HTTP/3 HEADERS frame whose QPACK section decodes to a ~1 GiB non-Huffman name length and is used to observe server-side failure; it illustrates how little wire data can target `new byte[length]`.

```java @Test public void test() throws Exception { EventLoopGroup group = new MultiThreadIoEventLoopGroup(1, NioIoHandler.newFactory()); try { X509Bundle cert = new CertificateBuilder() .subject("cn=localhost") .setIsCertificateAuthority(true) .buildSelfSigned();

QuicSslContext serverContext = QuicSslContextBuilder.forServer(cert.toTempPrivateKeyPem(), null, cert.toTempCertChainPem()) .applicationProtocols(Http3.supportedApplicationProtocols())…

WID-SEC-W-2026-1372 — Netty: Mehrere Schwachstellen

Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in Netty ausnutzen, um Sicherheitsmaßnahmen zu umgehen, Daten zu manipulieren, vertrauliche Informationen offenzulegen oder einen Denial-of-Service-Zustand zu verursachen.
