Embedded Java with GCJ
Embedded Java with GCJ http://0-delivery.acm.org.innopac.lib.ryerson.ca/10.1145/1140000/11341... Embedded Java with GCJ Gene Sally Abstract You don't always need a Java Virtual Machine to run Java in an embedded system. This article discusses how to use GCJ, part of the GCC compiler suite, in an embedded Linux project. Like all tools, GCJ has benefits, namely the ability to code in a high-level language like Java, and its share of drawbacks as well. The notion of getting GCJ running on an embedded target may be daunting at first, but you'll see that doing so requires less effort than you may think. After reading the article, you should be inspired to try this out on a target to see whether GCJ can fit into your next project. The Java language has all sorts of nifty features, like automatic garbage collection, an extensive, robust run-time library and expressive object-oriented constructs that help you quickly develop reliable code. Why Use GCJ in the First Place? The native code compiler for Java does what is says: compiles your Java source down to the machine code for the target. This means you won't have to get a JVM (Java Virtual Machine) on your target. When you run the program's code, it won't start a VM, it will simply load and run like any other program. This doesn't necessarily mean your code will run faster. Sometimes you get better performance numbers for byte code running on a hot-spot VM versus GCJ-compiled code. -

Evil Pickles: Dos Attacks Based on Object-Graph Engineering∗
Evil Pickles: DoS Attacks Based on Object-Graph Engineering∗ Jens Dietrich1, Kamil Jezek2, Shawn Rasheed3, Amjed Tahir4, and Alex Potanin5 1 School of Engineering and Advanced Technology, Massey University Palmerston North, New Zealand [email protected] 2 NTIS – New Technologies for the Information Society Faculty of Applied Sciences, University of West Bohemia Pilsen, Czech Republic [email protected] 3 School of Engineering and Advanced Technology, Massey University Palmerston North, New Zealand [email protected] 4 School of Engineering and Advanced Technology, Massey University Palmerston North, New Zealand [email protected] 5 School of Engineering and Computer Science Victoria University of Wellington, Wellington, New Zealand [email protected] Abstract In recent years, multiple vulnerabilities exploiting the serialisation APIs of various programming languages, including Java, have been discovered. These vulnerabilities can be used to devise in- jection attacks, exploiting the presence of dynamic programming language features like reflection or dynamic proxies. In this paper, we investigate a new type of serialisation-related vulnerabilit- ies for Java that exploit the topology of object graphs constructed from classes of the standard library in a way that deserialisation leads to resource exhaustion, facilitating denial of service attacks. We analyse three such vulnerabilities that can be exploited to exhaust stack memory, heap memory and CPU time. We discuss the language and library design features that enable these vulnerabilities, and investigate whether these vulnerabilities can be ported to C#, Java- Script and Ruby. We present two case studies that demonstrate how the vulnerabilities can be used in attacks on two widely used servers, Jenkins deployed on Tomcat and JBoss. -

Baumgarten Die Dissertation wurde am 27.6.2006, bei der Technischen Universität München ein- gereicht und durch die Fakultät für Elektrotechnik und Informationstechnik am 8.12.2006 angenommen. ii Abstract Der Entwurf von Software für eingebettete Systeme wird sowohl durch die Systemum- gebung als auch durch das System selbst stark beeinflusst. Beide Faktoren reduzieren die Wiederverwendbarkeit und die Erweiterbarkeit der Software in erheblichem Maße. Insbesondere können wirtschaftliche Überlegungen mitunter hohe Anforderungen an das Design stellen. Eine Lösung dieser Problematik kann nur mit klar definierten Abstrakti- onsebenen und geeigneten Schnittstellen zur Integration ermöglicht werden. Mit MetaC wird in dieser Arbeit eine Spracherweiterung vorgestellt, die neue Konzepte bietet, um die speziellen Anforderungen querschneidender Strukturen von eingebetteter Software anzusprechen.
