As a current main end-to-end communication protocol there are a few vulnerabilities in TCP specification. The paper discusses the theory and vulnerability of TCP persist timer and analyzes the implementation of it in Linux. The vulnerability can lead to the infamous DOS attack. In the end of the paper we give two solutions to defense this type of DOS attack through modifying Linux kernel codes or through application implementation.
