Add tests for integer overflow

oneapi-src / unified-memory-framework

A library for constructing allocators and memory pools. It also contains broadly useful abstractions and utilities for memory management. UMF allows users to manage multiple memory pools characterized by different attributes, allowing certain allocation types to be isolated from others and allocated using different hardware resources as required.

The application performs a calculation that can produce an integer overflow or underflow. This can happen when an application's logic assumes that a resulting value will always be larger or smaller than the original value. This can lead to other weaknesses because the size of the buffer is incorrectly calculated, such as a buffer overflow.

Use the following guidelines to test for integer overflow:

Identify sections of the site that perform integer arithmetic with user-supplied values.
Provide large negative and positive values and inspect the result.
This test fails if the result is negative when it should be positive, or vice-versa.
