This paper proposes a novel static analysis framework based on symbolic operations to analyze and detect array index and pointer bounds. 本文提出了基于符号运算的静态结构化分析框架,对数组索引以及指针边界进行分析和检测。
The abstract symbol table-based memory model can overcome main problems of memory models for symbolic execution very well, including the problem of pointer and aliasing, type-unsafe memory accesses and data without concrete size. 基于抽象符号表的内存模型能够很好地解决面向符号执行的内存模型面临的主要问题,包括指针和别名问题、类型不安全的内存访问和大小不确定的数据。
