摘　　要：针对现有动态更新方法缺乏处理已存在错误状态的被更新软件的能力,该文基于POLUS的动态更新框架,分别提出在动态更新性能时处理线程死锁、内存管理错误和数据结构错误的启示性修复方案。实验结果证明,各修复方案都能够成功地排除错误状态,实现修复目的。Most existing dynamic updating approaches can not recover the target application from some tainted states which are imported by the vulnerabilities. The lack of tainted states recovery can cause huge reliability disasters. This paper proposes to recover the tainted state during DSU based on the POLUS framework. Recovery solutions of deadlock, buffer overflow and data struct repair are presented and the experiments show that these approaches are viable.
