TECHNIQUES OF ADDING SECURITY PATCHES TO EMBEDDED SYSTEMS

摘要

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be an embedded-system device. The embedded-system device intercepts a call to a target function in a system dynamic library. The embedded-system device invokes an intermediate function in an intercept dynamic library and corresponding to the target function. The embedded-system device refrains from calling the target function or calling the target function with one or more modified parameters.
