### Summary An unsafe reading of environment file could potentially cause a denial of service in Netty. When loaded on an Windows application, Netty attemps to load a file that does not exist. If an attacker creates such a large file, the Netty application crash. ### Details When the library netty is loaded in a java windows application, the library tries to identify the system environnement in which it is executed. At this stage, Netty tries to load both `/etc/os-release` and `/usr/lib/os-release` even though it is in a Windows environment. <img width="364" alt="1" src="https://github.com/user-attachments/assets/9466b181-9394-45a3-b0e3-1dcf105def59"> If netty finds this files, it reads them and loads them into memory. By default : - The JVM maximum memory size is set to 1 GB, - A non-privileged user can create a directory at `C:\` and create files within it. <img width="340" alt="2" src="https://github.com/user-attachments/assets/43b359a2-5871-4592-ae2b-ffc40ac76831"> <img...
