stack smashing protection

Compiler stack protection technology in GCC Buffer overflow, represented by stack overflow, has become the most common security vulnerability. Security problems are common. As early as 1988, Morris, a graduate student in the Computer Science

Stack-Buffer Overflow Vulnerability I plan to write this article because I have read a paper on the Internet about the buffer overflow and stack destruction vulnerability to execute malicious programs. See reference 1 for this paper. This article

There was a time when I tried to reproduce a buffer overflow problem when I learned about these compilation options. I was experimenting on Ubuntu 12.04, and the GCC version was 4.6.3. What I did was simple:   code is as follows

IntroductionROP (return-oriented programming), or "return-oriented programming technology". The core idea is to find a suitable instruction fragment (gadget) in the existing function in the whole process space, and to splice each gadget through a

IntroductionIn June 2015, a new Memory corruption exploit mitigation named Safestack is merged into the LLVM Development Branch by Pe ter Collingbourne from Google and would be available to the upcoming 3.8 release. Safestack was developed as part

In the basic software security experiment, buffer overflow is a basic and classic problem. The most basic buffer overflow is the reasonable construction of input data, so that the amount of input data exceeds the size of the original buffer, so as

Iv. Stack CanariesFirst look at the evolution history of Stack Canaries:Stack Guard was the first to be implemented using the Canaries probe, which was released as an extension of GCC in 1997. The original version of Stack Guard uses 0x00000000 as

Fashion and fashion: the most fashionable Buffer Overflow targetIn today's operating systems, memory defect vulnerabilities have become increasingly difficult to mine, and stack protection measures have made the original Buffer Overflow exploitation
