The Code Review Patch challenges are designed to enhance your ability to identify security vulnerabilities by reviewing code. In these challenges, you are provided with both the vulnerable code and the patch that fixes the issue. Your initial task is to detect the vulnerability on your own without consulting the patch. This exercise helps sharpen your skills in spotting common coding mistakes that lead to security flaws. Once you have made your assessment, you can then look at the provided patch to see if you correctly identified the problem or to understand the exact nature of the issue if you couldn't find it initially.

For this particular challenge, you are tasked with finding the first occurrence of the vulnerability. This exercise not only tests your ability to read and analyze code but also reinforces the importance of understanding how patches address specific security concerns. By examining both the vulnerable code and the patch, you can gain a deeper understanding of secure coding practices and the types of vulnerabilities that commonly occur in software development.
