US 2014/0181980 A1 · SYSTEM AND METHOD FOR PROTECTION FROM BUFFER OVERFLOW VULNERABILITY DUE TO PLACEMENT NEW CONSTRUCTS IN C++

Abstract

Systems and methods for protection from buffer overflow vulnerability due to placement new constructs in C++ are provided. A system for protecting from buffer overflow vulnerability due to placement new constructs, comprises a compiler which is capable of receiving a program including a placement new instruction, and runtime which is capable of receiving binary code from the compiler and determining whether the program includes the placement new instruction and whether the placement new instruction would lead to buffer overflow, wherein the runtime is linked to a library including methods for preventing the buffer overflow, and selects a method for preventing the buffer overflow if the runtime determines that the placement new instruction would lead to the buffer overflow.

Dependent claims

A method for protecting from buffer overflow vulnerability due to placement new constructs, the method comprising:

detecting whether there is an instruction in a program which would lead to buffer overflow;
checking whether the instruction is a placement new instruction which would result in an object overwriting contents in a memory area;
and
selecting a method for preventing the buffer overflow if the instruction is the placement new instruction which would result in the object overwriting the contents in the memory area, wherein the selected method prevents the buffer overflow from occurring by controlling an allocation of the object to permit placement of the object in one or more memory regions.
