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...

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...

CVE-2026-104043
