Security update for netty, netty-tcnative
Severity
Important
Notes
Title of the patch: Security update for netty, netty-tcnative
Description of the patch: This update for netty, netty-tcnative fixes the following issues:
Upidate to 4.1.132:
- CVE-2026-33870: incorrectly parses quoted strings in HTTP/1.1 can lead to request smuggling (bsc#1261031).
- CVE-2026-33871: sending a flood of CONTINUATION frames can lead to a denial of service (bsc#1261043).
Changelog:
- Upgrade to upstream version 4.1.132
* Fixes:
+ Fix Incorrect nanos-to-millis conversion in epoll_wait EINTR
retry loop
+ Make RefCntOpenSslContext.deallocate more robust
+ HTTP2: Correctly account for padding when decompress
+ Fix high-order bit aliasing in HttpUtil.validateToken
+ fix: the precedence of + is higher than >>
+ AdaptiveByteBufAllocator: make sure byteBuf.capacity() not
greater than byteBuf.maxCapacity()
+ AdaptivePoolingAllocator: call unreserveMatchingBuddy(...)
if byteBuf initialization failed
+ Don't assume CertificateFactory is thread-safe
+ Fix HttpObjectAggregator leaving connection stuck after 413
with AUTO_READ=false
+ HTTP2: Ensure preface is flushed in all cases
+ Fix UnsupportedOperationException in readTrailingHeaders
+ Fix client_max_window_bits parameter handling in
permessage-deflate extension
+ Native transports: Fix possible fd leak when fcntl fails.
+ Kqueue: Fix undefined behaviour when GetStringUTFChars fails
and SO_ACCEPTFILTER is supported
+ Kqueue: Possible overflow when using
netty_kqueue_bsdsocket_setAcceptFilter(...)
+ Native transports: Fix undefined behaviour when
GetStringUTFChars fails while open FD
+ Epoll: Add null checks for safety reasons
+ Epoll: Use correct value to initialize mmsghdr.msg_namelen
+ Epoll: Fix support for IP_RECVORIGDSTADDR
+ AdaptivePoolingAllocator: remove ensureAccessible() call in
capacity(int) method
+ Epoll: setTcpMg5Sig(...) might overflow
+ JdkZlibDecoder: accumulate decompressed output before firing
channelRead
+ Limit the number of Continuation frames per HTTP2 Headers
(bsc#1261043, CVE-2026-33871)
+ Stricter HTTP/1.1 chunk extension parsing (bsc#1261031,
CVE-2026-33870)
+ rediff
- Upgrade to upstream version 4.1.131
+ NioDatagramChannel.block(...) does not early return on failure
+ Support for AWS Libcrypto (AWS-LC) netty-tcnative build
+ codec-dns: Decompress MX RDATA exchange domain names during
DNS record decoding
+ Buddy allocation for large buffers in adaptive allocator
+ SslHandler: Only resume on EventLoop if EventLoop is not
shutting down already
+ Wrap ECONNREFUSED in PortUnreachableException for UDP
+ Bump com.ning:compress-lzf (4.1)
+ Fix adaptive allocator bug from not noticing failed allocation
+ Avoid loosing original read exception
+ Backport multiple adaptive allocator changes
- Upgrade to version 4.1.130
- Upgrade to version 2.0.75 Final
* No formal changelog present
* Needed by netty >= 4.2.11
