DEBIAN-CVE-2026-54463

websocket-driver is a WebSocket protocol handler with pluggable I/O. Prior to 0.8.1, draft versions of the WebSocket protocol in websocket-driver include a length header that allows an arbitrarily large integer to be encoded as bytes with the high bit set, and a server or client can send an...

DEBIAN-CVE-2026-54465

websocket-driver is a WebSocket protocol handler with pluggable I/O. Prior to 0.8.1, when websocket-driver is used to implement a WebSocket server on top of a TCP server using WebSocket::Driver.server or to complement a WebSocket client, a peer can make a single connection consume an unbounded...

CVE-2026-44891 Netty: Denial of Service via Unbounded Headers in StompSubframeDecoder

Netty is a network application framework for development of protocol servers and clients. Prior to 4.1.136.Final and 4.2.16.Final, io.netty.handler.codec.stomp.StompSubframeDecoder fails to limit the total number of headers or their cumulative size per frame, and the maxLineLength parameter only...

CVE-2026-44891

CVE-2026-44891 affects Netty’s StompSubframeDecoder. Prior to 4.1.136.Final and 4.2.16.Final, StompSubframeDecoder does not cap total headers or cumulative size per frame; maxLineLength only bounds individual header lines. An attacker can submit many small headers that accumulate in DefaultStompH...

CVE-2026-54463

The CVE-2026-54463 issue affects the websocket-driver WebSocket protocol handler (prior to version 0.8.1). The root cause is a length header in draft WebSocket protocol frames that can encode an arbitrarily large integer, allowing a peer to send an indefinite sequence of 0x80+ bytes that are pars...

CVE-2026-55254 NCalc: Denial of Service via Unbounded and Non-Terminating Factorial Evaluation

NCalc is a fast, lightweight expression evaluator for .NET. Prior to 6.1.1, the factorial operator implementation in src/NCalc.Core/Helpers/MathHelper.cs permits specially crafted expressions with extremely large factorial operands, causing excessive CPU consumption or a non-terminating loop due ...
