Abstract:

A common security problem is the residual--data or access capability left after the completion of a process and not intended for use outside the context of that process. If the residual becomes accessible to another process, a security error may result. A major source of such residuals is improper or incomplete allocationdeallocation processing. The various types of allocation deallocation residuals are discussed in terms of their characteristics and the manner in which they occur, and a semiautomatable search strategy for detecting sources of these residuals is presented.
