Software Model-Checking: Benchmarking and Techniques for Buffer Overflow Analysis Kelvin Ku Master of Science Graduate Department of Computer Science University of Toronto 2008 Software model-checking based on abstraction-refinement has recently achieved widespread success in verifying critical properties of real-world device drivers. We believe this success can be replicated for the problem of...

Isolated superfused rat atria release [H]acetylcholine when depolarized with 57 mM potassium. The depolarization-induced overflow of [H]acetylcholine is markedly inhibited by micromolar concentrations of epinephrine and norepinephrine. The a,-selective adrenergic agonist methoxamine also inhibits tritium overflow, but the «2-selective adrenergic agonist clonidine and the 0-adrenergic agonist is...

-Since the first buffer overflow problem occurred, many detection techniques have been presented. These techniques are effective in detecting most attacks, but some attacks still remain undetected. In order to be more effective, a memory-size-assisted buffer overflow detection(MBOD) is presented. The key feature of buffer overflow is that the size of the source memory is bigger than the size of...

unaccounted-for-water is a misleading term long used by water industry. unaccounted-for-water includes unmeasured volume of water that run out of access from supply to end consumer and consequently leads no revenue for supplier. examples of water losses are: meter inaccuracies, illegal connection and unauthorized usage of water, abnormal meter reading, reservoir seepage and leakage, reservoir o...

In this report we deal with the time to buffer overflow in a finite-buffer queue with MMPP (Markov-modulated Poisson process) arrivals. The results include a closed-form formula for the transform of the distribution of the time to buffer overflow. The main benefit of this formula is that, using properties of the transform, we can easily compute the average overflow time and all the moments (var...

In this paper a study on the buffer overflow period in a finite-buffer queue is presented. A special attention is paid to the autocorrelation and batch arrivals, which are supposed to mimic the properties of real arrival processes. Using the batch Markovian arrival process, formulas for the duration of the first, subsequent and stationary overflow periods, as well as formulas for the distributi...

MCAIDS-Machine Code Analysis Intrusion Detection System for blocking code-injection buffer overflow attack messages targeting at various Internet services such as web service. With the increasing access of Internet,the Internet threat takes a form of attack, targetting individuals users to gain control over network and data. Buffer overlow is one of the most occuring security vulnerability in c...

In this paper we study the rare event of overflow in a Markov fluid queue with finite buffer and many input sources. The probability of this rare event will be estimated by simulations. We present a highly efficient importance sampling procedure to speed up the simulations. The implemented change of meausure is suggested after a large deviations analysis of the overflow probability. This analys...

As a collaborative effort among government aerospace research laboratories, an advanced version of a widely used computational fluid dynamics code, OVERFLOW2.1z, was recently released. This latest version includes additions to model multiple flexible, rotating blades. This paper describes how the OVERFLOW code is applied to improve the accuracy of airload computations from the linear lifting li...
