Is it secure to use malloc?

Question

Somebody told me that allocating with malloc is not secure anymore, I\'m not a C/C++ guru but I\'ve made some stuff with malloc and C/C++. Does anyone know about what risks

Answer 1

[...] C/C++ it is a well known insecure language. [...]

Actually, that's wrong. Actually, "C/C++" doesn't even exist. There's C, and there's C++. They share some (or, if you want, a lot of) syntax, but they are indeed very different languages.

One thing they differ in vastly is their way to manage dynamic memory. The C way is indeed using malloc()/free() and if you need dynamic memory there's very little else you can do but use them (or a few siblings of malloc()).
The C++ way is to not to (manually) deal with dynamic resources (of which memory is but one) at all. Resource management is handed to a few well-implemented and -tested classes, preferably from the standard library, and then done automatically. For example, instead of manually dealing with zero-terminated character buffers, there's std::string, instead of manually dealing with dynamically allocated arrays, there std:vector, instead of manually dealing with open files, there's the std::fstream family of streams etc.
