Address space layout randomization (ASLR) is a computer security technique involved in preventing exploitation of memory corruption vulnerabilities. In order to prevent an attacker from reliably jumping to, for example, a particular exploited functio…

A system and method for address space layout randomization ("ASLR") for a Windows operating system is disclosed. The address space layout includes one or more memory regions that are identified and then a particular implementation of the system…

The present application relates generally to laying out address space for execute-in-place code and, more specifically, to a method for address space layout randomization for such code. Ahead of executing a program, executable code for which is store…

A system and method in one embodiment includes modules for detecting an access attempt to a critical address space (CAS) of a guest operating system (OS) that has implemented address space layout randomization in a hypervisor environment, identifying…

墙外通道:http://thinkiii.blogspot.com/2014/02/arm64-linux-kernel-virtual-address-space.html Now let's talk about the Linux kernel virtual address space on 64-bit ARM CPU. You can find information about ARMv8 in ARM official website. http://www.arm.com/pr…

http://thinkiii.blogspot.jp/2014/02/arm32-linux-kernel-virtual-address-space.html   The 32-bit ARM CPU can address up to 2^32 = 4GB address*. It's not big enough in present days, since the size of available DRAM on computing devices is growing fast a…

最近写一个关于单片机播放音乐的程序,出现如下错误: *** ERROR L107: ADDRESS SPACE OVERFLOW ... ... Program Size: data=167.6 xdata=0 code=5314 Target not created 仔细想想,我用的是AT89C52,片上RAM有256字节,应该不会overflow啊,如果将Keil的编译模式选用compact或large则编译可以顺利通过,但生成的HEX文件无法使用. 关于此问题,网上的有关信息如下: Kei…

Virtual addresses from multiple address spaces are translated to real addresses in main memory by generating for each virtual address an address space identifier (AID) identifying its address space. Then, the virtual address and its AID are used to o…
