/DYNAMICBASE (Use address space layout randomization)

Specifies whether to generate an executable image that can be randomly rebased at load time by using the address space layout randomization (ASLR) feature of Windows that was first available in Windows Vista.

Syntax

/DYNAMICBASE[:NO]

Remarks

The /DYNAMICBASE option modifies the header of an executable image, a .dll or .exe file, to indicate whether the application should be randomly rebased at load time, and enables virtual address allocation randomization, which affects the virtual memory location of heaps, stacks, and other operating system allocations. The /DYNAMICBASE option applies to both 32-bit and 64-bit images. ASLR is supported on Windows Vista and later operating systems. The option is ignored by earlier operating systems.

By default, /DYNAMICBASE is enabled. To disable this option, use /DYNAMICBASE:NO. The /DYNAMICBASE option is required for the /HIGHENTROPYVA option to have an effect.
