The -highentropyva compiler option tells the Windows kernel whether a particular executable supports high entropy Address Space Layout Randomization (ASLR).
Syntax
-highentropyva[+ | -]
Arguments
| + | - | This option specifies that a 64-bit executable or an executable that is marked by The -platform:anycpu compiler option supports a high entropy virtual address space. The option is disabled by default. Use -highentropyva+ or -highentropyva to enable it. |
Remarks
The -highentropyva option enables compatible versions of the Windows kernel to use higher degrees of entropy when randomizing the address space layout of a process as part of ASLR. Using higher degrees of entropy means that a larger number of addresses can be allocated to memory regions such as stacks and heaps. As a result, it is more difficult to guess the location of a particular memory region.
When The -highentropyva compiler option is specified, the target executable and any modules that it depends on must be able to handle pointer values that are larger than 4 gigabytes (GB) when they are running as a 64-bit process.
To set this compiler option in the Visual Studio development environment
1.Open the project's Properties page.
2.Click the Build property page.
3.Add the option in the "User-Defined Command Line options" property
