In the following, I present some techniques to achieve an out-of-bounds heap write operation after an overflowing size computation that involves one or more multiplications. This is still very far away from an actual exploit which achieves code execution, but a proof-of-concept showing the out-...
value computation, whether that computation itself wraps or not (it would wrap the same for each iteration) isn't covered. > > I wonder if we maybe want to record an "original" iv->base > > to be used for code generation (and there only the unexpanded form) > > and a variant used...

4 Computation of Cluster Size In this section, we show how the cluster size c can be chosen when the total amount of allocated memory is constrained by a quota q. The choice of c pri- marily involves a space-randomness tradeoff. The smaller the reserved space, the better the virtual and...
An interdisciplinary approach 125 As mentioned earlier, this controller has more advan- tages than the one shown in 2015 [6], since the previous controller required full knowledge of rcrit in the control computation, which can be a problem in addition to the singularity problem and the ...
or other communicated value, is written to, or read from, during execution of said computer program: b) encoding said data, even if said data overflows said buffer, using an encoding selected from a plurality of encodings, to result in encoded data; said plurality of encodings include a spe...
24. The method of claim 1 wherein said step of encoding comprises the steps of: responding to the identification of an access to memory by: generating a pseudo-random constant; and encoding a data value to be stored in memory on the basis of said pseudo-random constant. 25. The method...
in the previous section to find the sign configuration diagram for $latex {\mathcal{P}_k}&fg=000000$. In the course of this procedure, whenever we need to know the sign of the leading coefficient of a polynomial, we use the value already guessed for it. Finally, we check whether any...
