To prevent buffer overflows, there are several protections available such as using Canary values, ASLR, DEP, NX. But, where there is a will, there is a way. I am researching on the various methods an ...
In computer security, my areas of interest include x86 processors, binary exploitation and reverse engineering. I'm also interested in the certain aspects of the minix and the linux kernel(memory ...
I'm looking for a very simple application that has an intentional Buffer Overflow embedded in it. I'm assuming this possible in systems where DEP and ASLR are not being used Ideally (and if ...
At IEEE Security & Privacy, the blind return-oriented programming attack (blind ROP) was just introduced. In some sense, this is just another variation on ROP attacks -- but the blind ROP attack ...
What set of GCC options provide the best protection against memory corruption vulnerabilities such as Buffer Overflows, and Dangling Pointers? Does GCC provide any type of ROP chain mitigation? Are ...
The students are skeptical that turning off non-executable stacks, turning off canaries and turning off ASLR represents a realistic environment. If PaX, DEP, W^X, etc., are effective at stopping ...
I am developing a vending machine and want to make it secure. In a comment to my previous question, @Polynomial said "Vending machines (and similar devices) can often be pwned via buffer overflows on ...
Buffer overflow occurs because it writes to memory spaces that are used by, or will be used by other parts of the program. Computer programs usually write to the memorylocation that has been ...
perhaps all of us use no-Script when we visit untrusted web pages to block all scripts plugins etc. but still there is something beside plain HTML codes that we don't block; SSL connection! in Https ...
