![]() For example, if the programmer declares an array char buffer, C will not automatically throw an error if the programmer tries to access buffer. A particular weakness that we will discuss is the absence of automatic bounds-checking for array or pointer accesses. Furthermore, C is also a very old language, meaning that there are several legacy systems, which are old codebases written in C that are still maintained and updated. However, buffer overflows are not unique to C, as C++ and Objective-C both suffer from these vulnerabilities as well.Ĭ is a low-level language, meaning that the programmer is always exposed to the bare machine, one of the reasons why C is such a popular systems language. Buffer overflow vulnerabilities are a particular risk in C, and since C is an especially widely used systems programming language, you might not be surprised to hear that buffer overflows are one of the most pervasive kind of implementation flaws around. We’ll start our discussion of vulnerabilities with one of the most common types of errors - buffer overflow (also called buffer overrun) vulnerabilities.
