Buffer Overflow Protection - Bounds Checking

Bounds Checking

Bounds checking is a compiler-based technique that adds run-time bounds information for each allocated block of memory, and checks all pointers against those at run-time. For C and C++, bounds checking can be performed at pointer calculation time or at dereference time.

Implementations of this approach use either a central repository, which describes each allocated block of memory, or fat pointers, which contain both the pointer and additional data, describing the region that they point to.

Famous quotes containing the word bounds:

    Nature seems at each man’s birth to have marked out the bounds of his virtues and vices, and to have determined how good or how wicked that man shall be capable of being.
    François, Duc De La Rochefoucauld (1613–1680)
