Identify the dynamic libraries that you want to test. You can use tools like ldd or objdump to list the libraries that an executable depends on. Use a dynamic analysis tool to monitor the behavior of the libraries at runtime. This can include tools like strace, ltrace, or ptrace. These tools allow you to see what system calls the library is making, what files it is accessing, and what network connections it is making. Use a memory analysis tool to analyze the memory usage of the library at runtime. This can include tools like valgrind or AddressSanitizer. These tools can help you detect memory leaks, buffer overflows, and other memory-related vulnerabilities. Use a fuzzing tool to test the library's input validation. This can include tools like AFL or American Fuzzy Lop. These tools generate a large number of inputs and test how the library responds to them. This can help you find input validation vulnerabilities, such as buffer overflows or format string vulnerabilities.
