摘要：
A method for preventing subversion of address space layout randomization (ASLR) in a computing device is described. An unverified module attempting to load into an address space of memory of the computing device is intercepted. Attributes associated with the unverified module are analyzed. A determination is made, based on the analyzed attributes, whether a probability exists that the unverified module will be loaded into a number of address spaces that exceeds a threshold. The unverified module is prevented from loading into the address space if the probability exists that the unverified module will be loaded into a number of address spaces that exceeds the threshold.
