Course

The "Code Review Patch" lab is designed to help you identify security vulnerabilities in code by providing both the original vulnerable code and its patched version. Initially, you are encouraged to find the issue without looking at the patch, which sharpens your analytical skills and understanding of code security. If you struggle to find the vulnerability or wish to confirm your findings, you can then review the patch to see the modifications made to secure the code.

In this specific example, the code in question is part of the Apache Submarine project, particularly within the `YamlEntityProvider` class. The patch addresses several issues, including the replacement of direct calls to the `Yaml` class with `YamlUtils`, and the proper handling of input streams and writers to avoid resource leaks. These changes enhance the security and stability of the code, demonstrating the practical importance of thorough code reviews and effective patching.
