![]() ![]() ![]() Applications patched by IntPatch have a negligible runtime performance loss which is averaging about 1%. ![]() It has caught all 46 previously known IO2BO vulnerabilities in our test suite and found 21 new bugs. Do integer overflows also buffer overflow Hi, Im currently learning about c and the classic vulnerabilities that arise. We evaluate IntPatch on a number of real-world applications. Moreover, IntPatch provides an interface for programmers to facilitate checking integer overflows. IntPatch utilizes classic type theory and dataflow analysis framework to identify potential IO2BO vulnerabilities, and then instruments programs with runtime checks. Buffer overflow is a common type of cyber attack that can have serious consequences for individuals and organizations. In this paper, we present the design and implementation of IntPatch, a compiler extension for automatically fixing IO2BO vulnerabilities in C/C++ programs at compile time. Buffer overflows also occur at a similar level. As we have stated, an integer overflow is produced when the result of an operation is too large for the space allocated to it, causing either a wraparound, undefined behavior or other errors. When this occurs, the value may wrap to become a very small or negative number. Automatically identifying and fixing this kind of vulnerability are critical for software security. Integer overflows and buffer overflowsare somewhat similar bugs. An integer overflow or wraparound occurs when an integer value is incremented to a value that is too large to store in the associated representation. The Integer-Overflow-to-Buffer-Overflow (IO2BO) vulnerability is an underestimated threat. Chao Zhang, Tielei Wang, Tao Wei, Yu Chen, and Wei Zou A buffer overflow is dangerous when the vulnerable binary or program is a setuid binary, If you don’t know what setuid binaries are, read the provided link, but in general They are programs that run with capabilities of another user (usually root), But when that program is vulnerable to a buffer overflow it’s not a good thing anymore. ![]()
