PaX is an intrusion prevention system that provides the best protection mechanisms against memory corruption bugs. Some applications are not compatible with certain features (due to design or bad engineering) and therefore they have to be exempted from certain enforcements. It is also possible to use PaX in soft mode where none of the protection mechanisms are active by default - here paxctl can be used to turn them on for selected programs (e.g., network daemons, programs that process network data such as mail clients, web browsers, etc). PaX and paxctl work on ELF executables, both of the standard ET_EXEC and the newer ET_DYN kind (older PaX releases referred to the latter as ET_DYN executables, these days they are called Position Independent Executables or PIEs for short).
