2016-06-09docs: self-protection: rename "leak" to "exposure"Kees Cook1-10/+18
The meaning of "leak" can be both "untracked resource allocation" and "memory content disclosure". This document's use was entirely of the latter meaning, so avoid the confusion by using the Common Weakness Enumeration name for this: Information Exposure (CWE-200). Additionally adds a section on structure randomization. Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
