This will result in various attacks such buffer overflow which is the most common attack and leads to executing malicious programs or privilege escalation. Most compilers will ignore the overflow and store unexpected output or error. So, during an arithmetic operation, if the results require more than the allocated space (like 65535+1), the compiler may: Mostly in all programming languages, integers values are allocated limited bits of storage.įor example, we have a 16-bit integer value which may store an unsigned integer ranging from 0 to 65535, or signed integer ranging from -32768 to 32767. Integer overflow, also known as wraparound, occurs when an arithmetic operation outputs a numeric value that falls outside allocated memory space or overflows the range of the given value of the integer. Our main focus in this article will be integer overflow attack how it works, how it can lead to exploitation, and steps we can take to prevent it. Some software/programming related attacks include:Īpart from the above there are many other attacks which are related to programming and software. These vulnerabilities have a negative impact on the confidentiality, integrity, and availability of the asset.

Software threats have seen exponential growth over the last few years.
