CVE-2026-100661

A flaw was found in Netty's HTTP/3 codec. A remote, unauthenticated attacker can cause a Denial of Service DoS by sending a specially crafted stream of data to the QPACK integer decoder. Because the decoder fails to limit incoming continuation bytes, data accumulates indefinitely in memory while...

DEBIAN-CVE-2026-100666

Netty's HttpServerCodec io.netty:netty-codec-http in versions 4.2.0.Final through 4.2.16.Final and in versions up to and including 4.1.136.Final pairs each outbound response with an inbound request by calling pollMethod once per response, including for 1xx informational responses. If a client...

CVE-2026-100661

Netty's HTTP/3 codec io.netty:netty-codec-http3 versions 4.2.0.Final through 4.2.17.Final contain a denial-of-service vulnerability in the QPACK prefixed-integer decoder QpackUtil.decodePrefixedInteger, which does not bound the number of continuation bytes it will process. A remote, unauthenticat...

CVE-2026-100662

Netty's HTTP/3 codec io.netty:netty-codec-http3 versions 4.2.0.Final through 4.2.17.Final contain an uncontrolled resource consumption vulnerability in the QPACK encoder-stream instruction decoder QpackEncoderHandler, installed on the peer-initiated unidirectional QPACK encoder stream, type 0x02...

CVE-2026-100663

Netty's HTTP/3 codec io.netty:netty-codec-http3 from 4.2.2.Final through 4.2.17.Final does not special-case HTTP/1 CONNECT authority-form request-targets when converting HTTP/1 messages to HTTP/3 in HttpConversionUtil.toHttp3Headers. The authority-form target e.g., "CONNECT trusted.example:443" i...
