New AspectJ Pointcuts for Integer Overflow and Underflow Detection

摘要

Aspect-oriented Programming (AOP) appears to be a promising paradigm for software security hardening. Using AOP, security experts can be responsible for coding security properties, and developers can concentrate on the basic functionality of the program. AspectJ extends the Java programming language to implement crosscutting concerns modularly in general. In this paper, we have extended AspectJ with new pointcuts in order to detect integer overflows and underflows in Java. Integer overflows and underflows in Java occur silently without throwing an exception. A malicious user can exploit them to produce a security breach. Hence, we implement new pointcuts: addition, multiplication, and subtraction that allow to write advices around integer arithmetic operations to detect integer overflow and underflow and consequently prevent considerable number of security breaches.
