io.netty/netty-codec-http: Netty: Denial of Service via SPDY SETTINGS frame processing

A flaw was found in Netty, a network application framework. A remote attacker, by sending a specially crafted SPDY/3.1 SETTINGS frame, could cause the SPDY SETTINGS decoder to create a large number of map entries. This excessive processing and memory allocation can lead to a denial of service DoS...

netty: io.netty/netty-codec-http: Netty: Denial of Service via memory exhaustion in SPDY-to-HTTP codec

A flaw was found in Netty. A remote attacker can exploit a vulnerability in the SpdyHttpDecoder handler of Netty's SPDY-to-HTTP codec. When processing a client-initiated SYNSTREAM frame, the decoder fails to release allocated memory if the stream is reset or content limits are exceeded. This...

CVE-2026-55833

A flaw was found in Netty, a network application framework. A remote attacker could exploit a vulnerability in the SPDY header decoding process. By sending a specially crafted, small compressed header block, the attacker can cause it to expand significantly during decompression, leading to...

Uncontrolled Resource Consumption (Memory Leak)

io.netty, netty-codec-http is vulnerable to Uncontrolled Resource Consumption Memory Leak. The vulnerability is due to the SpdyHttpDecoder failing to release a pooled ByteBuf when processing specific SPDY SYNSTREAM frames that are later reset RSTSTREAM or exceed the configured maxContentLength,...

Netty: [SpdyHttpDecoder] ByteBuf Reference Leak on RST_STREAM Leads to Native Memory Exhaustion

The SpdyHttpDecoder handler in Netty's SPDY-to-HTTP codec allocates a pooled ByteBuf when processing a client-initiated SYNSTREAM frame with FLAGFIN=0, storing the partially-constructed FullHttpRequest in an internal map messageMap to accumulate subsequent DATA frames. When the remote peer sends ...

GHSA-MVH2-CRG5-V77C Netty SPDY zlib header block continues decoded expansion after maxHeaderSize truncation

Summary Netty SPDY header decoding continues inflating zlib-compressed header blocks after the raw header parser has already exceeded maxHeaderSize and marked the frame truncated. At commit b2d2137c4404af425bf9d5d601a62576f5c06925, a 12,253-byte compressed SPDY header block can declare and inflat...

Netty SPDY SETTINGS frame count materializes unbounded settings map

Summary Netty's SPDY SETTINGS decoder accepts a peer-declared SETTINGS entry count up to the 24-bit frame-length limit and materializes every unique setting ID in DefaultSpdySettingsFrame without an implementation-level count cap. A remote SPDY/3.1 peer can send one syntactically valid roughly 2...
