Buffer overflow attacks can be prevented by using modern operating systems, executable space protection, bounds checking, static code analysis, and avoid using C and C++ languages. The most famous buffer overflow attacks are SQL Slammer and The Morris Worm. Doing so would prevent the normal functioning of the program. A buffer overflow condition exists when a program attempts to put more data in a buffer than it can hold or when a program attempts to put data in a memory area. Threat actors exploit buffer overflows by overwriting the memory of the application. Who is vulnerable to buffer overflow attacks Certain coding languages are more susceptible to buffer overflow than others. Use Modern Operating Systems: Modern operating systems have runtime protections that help mitigate buffer overflow attacks, such as randomly rearranging the address space locations of the main data areas of a process, avoiding knowledge of the exact location of important executable codes and assign a binary value, whether it is "executable" or "non-executable" in a memory area, protecting the non-executable area from exploits. Doing so will prevent the execution of machine code in these regions. In fact, bounds checking in abstract data type libraries can reduce the occurrence of buffer overflows.Įxecutable Space Protection: Memory regions should be marked as non-executable. Static Code Analysis: Use static application analysis tools such as Kiuwan to scan your code for buffer overflow vulnerabilities.īounds Checking: Avoid using standard library functions that do not bound checked such as strcpy, scanf, and gets. These languages don’t allow direct access to memory.īuffer Overflow Protection: The security of executable programs should be executed by detecting buffer overflows on stack-allocated variables. Prefer using other programming languages such as Python, Java, and COBOL. Buffer Overflow Attack PreventionĪvoid Using C and C++ Languages: C/C++ are high-level programming languages that are vulnerable to buffer overflow attacks. This fraud was also convicted under the Computer Fraud and Abuse Act. The Morris Worm: It was a buffer overflow attack that occurred in 1988 and resulted in the compromise of more than 60,000 machines. The bug was spread like a wildfire that doubles the size of the buffer after every 8.5 seconds, resulting in a loss of mobile phone coverage and internet outages across the world. The attacker sends carefully crafted input to a web application in order to force the web application to execute arbitrary code that allows the attacker to take over the system being attacked. According to the mend.io WhiteSource Report, PHP, Javascript, Java, and. An attacker can use buffer overflow attacks to corrupt the execution stack of a web application. However, buffer overflows are not unique to C, as C++ and Objective-C both suffer from these vulnerabilities as well. SQL Slammer: In 2003, a bug – termed as SQL Slammer – was implanted in Microsoft SQL. XSS is commonly found among the top vulnerability list of leading coding languages.
