(bsc#1237037) * CVE-2025-25193: unsafe reading of environment files can lead to an application crash. (bsc#1237038) Update to netty version 4.1.118 and netty-tcnative version 2.0.70 Final. Other fixes: * Fix recycling in CodecOutputList. * StreamBufferingEncoder: do not send header frame with priority by default. * Notify event loop termination future of unexpected exceptions. * Fix AccessControlException in GlobalEventExecutor. * AdaptivePoolingAllocator: round chunk sizes up and reduce chunk release frequency. * Support BouncyCastle FIPS for reading PEM files. * Dns: correctly encode DnsPtrRecord. * Provide Brotli settings without com.aayushatharva.brotli4j dependency. * Make DefaultResourceLeak more resilient against OOM. * OpenSslSession: add support to defensively check for peer certs. * SslHandler: ensure buffers are never leaked when wrap(...) produces SSLException. * Correcly handle comments appended to nameserver declarations. * PcapWriteHandler: apply fixes so that the handler can append to an existing PCAP file when writing the global header. * PcapWriteHandler: allow output of PCAP files larger than 2GB. * Fix bugs in BoundedInputStream. * Fix HTTP header validation bug. * AdaptivePoolingAllocator: fix possible race condition in method offerToQueue(...). * AdaptivePoolingAllocator: make sure the sentinel object Magazine.MAGAZINE_FREED not be replaced. * Only try to use Zstd and Brotli if the native libs can be loaded. * Bump BlockHound version to 1.0.10.RELEASE. * Add details to TooLongFrameException message. * AdaptivePoolingAllocator: correctly reuse chunks. * AdaptivePoolingAllocator: don't fail when we run on a host with 1 core. * AdaptivePoolingAllocator: correctly re-use central queue chunks and avoid OOM issue. * Fix several memory management (leaks and missing checks) issues. ## Patch Instructions: To install this SUSE update use the SUSE recommended installation methods like YaST online_update or "zypper patch".
