PPT-Finite Buffer Fluid Networks with Overflows

Yoni Nazarathy Swinburne University of Technology Melbourne Stijn Fleuren and Erjen Lefeber Eindhoven University of Technology the Netherlands Talk Outline Background Open Jackson networks. More over buffer overflow vulnerabilities dominate the area of remote network penetra tion vulnerabilities where an anonymous Inter net user seeks to gain partial or total control of a host If buffer overflow vulnerabilities could be effectively eli 48 O B 1 Th finite Galois r Overflow Example.
