Notes

Title of the patch: Security update for netty

Description of the patch: This update for netty fixes the following issues: Update to upstream version 4.1.130. Security issues fixed: - CVE-2025-67735: lack of URI sanitization in `HttpRequestEncoder` allows for CRLF injection through a request URI and can lead to request smuggling (bsc#1255048). Other updates and bugfixes: - Version 4.1.130: * Update `lz4-java` version to 1.10.1 * Close `Channel` and fail bootstrap when setting a `ChannelOption` causes an error * Discard the following `HttpContent` for preflight request * Fix race condition in `NonStickyEventExecutorGroup` causing incorrect `inEventLoop()` results * Fix Zstd compression for large data * Fix `ZstdEncoder` not producing data when source is smaller than block * Make big endian ASCII hashcode consistent with little endian * Fix reentrancy bug in `ByteToMessageDecoder` * Add 32k and 64k size classes to adaptive allocator * Re-enable reflective field accesses in native images * Correct HTTP/2 padding length check * Fix HTTP startline validation * Fix `MpscIntQueue` bug - Build against the `org.jboss:jdk-misc` artifact that is implementing the `sun.misc` classes removed in Java 25

CVE-2025-67735 (GCVE-0-2025-67735)

Vulnerability from cvelistv5 – Published: 2025-12-16 00:19 – Updated: 2025-12-16 14:26

Title

Netty has a CRLF Injection vulnerability in io.netty.handler.codec.http.HttpRequestEncoder

Summary

Netty is an asynchronous, event-driven network application framework. In versions prior to 4.1.129.Final and 4.2.8.Final, the `io.netty.handler.codec.http.HttpRequestEncoder` has a CRLF injection with the request URI when constructing a request. This leads to request smuggling when `HttpRequestEncoder` is used without proper sanitization of the URI. Any application / framework using `HttpRequestEncoder` can be subject to be abused to perform request smuggling using CRLF injection. Versions 4.1.129.Final and 4.2.8.Final fix the issue.

Severity
