    en.wikipedia.org/wiki/Executable-space_protection

    PaX supplies mprotect() restrictions to prevent programs from marking memory in ways that produce memory useful for a potential exploit. This policy causes certain applications to cease to function, but it can be disabled for affected programs. PaX allows individual control over the following functions of the technology for each binary executable:
