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…
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 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…
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…

您可能想知道为什么VirtualAlloc在64K边界分配内存,即使页面粒度为4K. 你有Alpha AXP处理器,感谢你. 在Alpha AXP上,没有“加载32位整数”指令.要加载32位整数,实际上要加载两个16位整数并将它们组合起来. 因此,如果分配粒度小于64K,则重新定位在内存中的DLL 将需要每个可重定位地址两个修正:一个到高16位,一个到低16位.如果这改变了两半之间的进位或借位,事情会变得更糟.(例如,来自0x1234F000移动地址4K到0x12350000,这迫使这两个地址的…
