Original Post: Identifying Insecure C Code with Valgrind and Fixing with Snyk Code
The article emphasizes the foundational role of C and C++ in critical software development, especially in sectors like manufacturing and industrial applications, where performance and control over system resources are paramount. It highlights the prevalence of these languages in Japan, known for its manufacturing and industrial prowess.
However, the article also underscores the security challenges associated with C and C++, such as buffer overflows, use-after-free, and memory leaks, due to their lack of built-in safety features. It provides a practical example of a memory leak in C code and demonstrates how to identify and fix such vulnerabilities using tools like Valgrind. Additionally, it discusses more complex examples that reveal deeper security issues like path traversal and buffer overflows.
The article concludes by stressing the importance of secure coding practices in C and C++ and introduces Snyk, a static application security testing (SAST) tool that helps developers detect and address security vulnerabilities early in the development process.
