Memory issues
- [Instructor] Okay, I just want to quickly address some memory issues here. We'll continue to talk about memory issues as we continue through and we start talking about secure software and how we, you know, mitigate against certain types of attacks. But there are a couple of issues that can come up specifically with memory. Overflows. So the idea is each application has a certain amount of memory that is allotted to the application. And so, if that application tries or needs additional memory other than what's allocated, that's considered to be an overflow. And there's several ways that these sort of overflows can happen. One is an integer overflow. So let's say that I ask you for a value between one and five and you type in the number six. That's a value out of an expected range, right? It's a value that I don't expect and anticipate. So that's called an integer overflow. And that can simply, that's not necessarily tied into memory per se, but it can cause an application to…
