Reviewing Code for Integer Manipulation Vulnerabilities
Michael Howard · 2003
I'm not going to explain what an integer is, I assume you know what they are, and you know that there are basically two flavors—signed and unsigned—where signed integers have the high-bit set to 1 when the value is negative, this is a consequence of 2's complement arithmetic. And you also know there are different size integers, the most common being 64-bit, 32-bit, 16-bit, and 8-bit in length. That's all I'm going to say about integers, and for the purposes of this paper, that's all you need know.
