Secure Programming - C/C++ Strings

Thanks to for posting this sample chapter from “Secure Coding in C/C++” about common pitfalls with Strings in C/C++. While this is an age-old discussion, it’s obviously still valid since these issues still exist in modern software. If a more appropriate higher level language with an actual string type is available, it should be used. Knowing which tools to use and when to use them is an important aspect of being a developer. Experience and dogma have not made developers immune from mistakes and this article has great information on various types of issues that can arise from character arrays, different stack protection routines, and even the venerable std::basic_string class. I was unaware of the Stack Smashing Protector for GCC. Funny that this was released at this time, I was going to write an article demonstrating buffer overflows for a future article. With this sample chapter and a little old Phrack Article, I have a great base to start from.
