by the `InputStreamReader`, it will issue replacement characters in its charset decoding, which will fill up the line-buffer in the `BufferedReader.readLine()`, because the replacement character is

If an attacker creates such a large file, the Netty application crash.\n\n\n### Details\n\nWhen the library netty is loaded in a java windows application, the library tries to identify the system environnement in which it is executed.\n\nAt this stage, Netty tries to load both `/etc/os-release` and `/usr/lib/os-release` even though it is in a Windows environment. \n\n<img width=\"364\" alt=\"1\" src=\"https://github.com/user-attachments/assets/9466b181-9394-45a3-b0e3-1dcf105def59\">\n\nIf netty finds this files, it reads them and loads them into memory.\n\nBy default :\n\n- The JVM maximum memory size is set to 1 GB,\n- A non-privileged user can create a directory at `C:\\` and create files within it.\n\n<img width=\"340\" alt=\"2\" src=\"https://github.com/user-attachments/assets/43b359a2-5871-4592-ae2b-ffc40ac76831\">\n\n<img width=\"523\" alt=\"3\" src=\"https://github.com/user-attachments/assets/ad5c6eed-451c-4513-92d5-ba0eee7715c1\">\n\nthe source code identified :\nhttps://github.com/netty/netty/blob/4.1/common/src/main/java/io/netty/util/internal/PlatformDependent.java\n\nDespite the implementation of the function `normalizeOs()` the source code not verify the OS before reading `C:\\etc\\os-release` and `C:\\usr\\lib\\os-release`.\n\n### PoC\n\nCreate a file larger than 1 GB of data in `C:\\etc\\os-release` or `C:\\usr\\lib\\os-release` on a Windows environnement and start your Netty application.\n\nTo observe what the application does with the file, the security analyst used \"Process Monitor\" from the \"Windows SysInternals\" suite.

Furthermore, the exploitation works with defaults windows/AD settings.\n- Scope : \"Unchanged\" because only Netty is affected by the vulnerability.\n- Confidentiality : \"None\" because no data is exposed through exploiting the vulnerability.\n- Integrity : \"None\" because the explotation of the vulnerability does not allow editing, deleting or adding data elsewhere.\n- Availability : \"High\"
