We present a previously undisclosed vulnerability of Android OS which can be exploited by mounting a Denial-of-Service attack that makes devices become totally unresponsive. We discuss the characteristics of the vulnerability - which affects all versions of Android - and propose two different fixes, each involving little patching implementing a few architectural countermeasures. We also provide experimental evidence of the effectiveness of the exploit as well as of the proposed countermeasures

Heterogeneous Adaptable Reconfigurable Networked SystemS (HARNESS) is an experimental metacomputing system [L. Smarr, C.E. Catlett, Communications of the ACM 35 (6) (1992) 45-52] built around the services of a highly customizable and reconfigurable Distributed Virtual Machine (DVM). The successful experience of the HARNESS design team with the Parallel Virtual Machine (PVM) project has taught us both the features which make the DVM model so valuable to parallel programmers and the limitations imposed by the PVM design. HARNESS seeks to remove some of those limitations by taking a totally different approach to creating and modifying a DVM.
