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 allocation/deallocation 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.
