Security update for netty
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

"text": "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.",
