W X Write XOR Execute spoken as double u Exclusive or ex or ex ref http www.openbsd.org 33.html OpenBSD 3.3 release notes ref is the name of a Computer insecurity security feature present in the OpenBSD operating system . It is a memory computers memory protection policy whereby every paging page in a Process computer science process address space is either writable or executable, but not both simultaneously the name comes from the XOR Boolean logic Boolean operator . W X does not prevent these permissions from being requested by applications, write and executable permissions are not used as a matter of policy. The OpenBSD base system has been modified to comply with it. This alleviates some buffer overflow attacks, including the most common stack based attack by ensuring that the stack is not executable, arbitrary code injected into it will not execute but instead cause the program to terminate. W X first appeared in OpenBSD 3.3, released May 2003. Similar features are available for other operating systems, including the PaX and Exec Shield patches for Linux , and NetBSD 4 s implementation of PaX. W X is relatively simple on Central processing unit processor s which support fine grained page permissions, such as Sun Microsystems Sun s SPARC and SPARC64, AMD s AMD64 , Hewlett Packard s PA RISC , and HP s originally Digital Equipment Corporation s DEC Alpha Alpha some early Intel 64 processors lacked the NX bit required for W X, but this appeared in later chips.
