Astra Linux – Vulnerability in Netty

The Snappy frame decoder function does not limit the chunk length, which can lead to excessive memory usage. In addition, it may also buffer reserved skipable chunks until the entire chunk is received, which can also result in excessive memory usage. This vulnerability can be exploited by providi...

Netty: Denial of Service in XmlFrameDecoder via CPU Exhaustion

Summary An attacker can cause Denial of Service by sending a specially crafted malicious XML payload e.g., repeated . Because the parser state is not saved between decode invocations, an attacker can trickle-feed a payload of / characters. This forces the decoder to repeatedly rescan the entire...

AZL-93096 CVE-2026-16473 affecting package sbc 2.0-6

A flaw was found in the sbc library BlueZ SBC codec. An off-by-one error in the SBC frame decoder allows a crafted audio payload to trigger a one-byte heap out-of-bounds read. This could allow an adjacent attacker streaming Bluetooth audio to read a single byte of adjacent heap memory...

CVE-2026-55833 Netty SPDY zlib header block continues decoded expansion after maxHeaderSize truncation

Netty is a network application framework for development of protocol servers and clients. Prior to 4.1.136.Final and 4.2.16.Final, Netty SPDY header decoding continues inflating zlib-compressed header blocks after the raw header parser has exceeded maxHeaderSize and marked the frame truncated in...

netty: io.netty/netty-codec-compression: io.netty/netty-codec: Netty: Denial of Service via excessive memory allocation in LZ4FrameDecoder

A flaw was found in Netty, an asynchronous, event-driven network application framework. A remote attacker can exploit this vulnerability by sending a specially crafted LZ4 compressed data stream. This can cause the Lz4FrameDecoder to allocate a large amount of memory up to 32 MB per block before...
