A comparison of publicly available tools for dynamic buffer overflow prevention. Of 7th Nordic Workshop on Secure IT Systems, 2002. A comparison of publicly available tools for static intrusion prevention. present a comprehensive overview of tools of both types.

Approaches to detect buffer over flow attacks can be divided into two groups: static techniques that detect potential buffer overruns by examining program’s source code and dynamic techniques that protect programs at run-time.

A reliable method called “heap spraying” is described at the end of the presentation. 2006 setjmp – used for exception handling (jump to global error handling code in case of error)

Windows media player bitmaps (skins) – heap overflow, Feb.Stack buffer overflow bugs are caused when a program writes more data to a buffer located on the stack than what is actually allocated for that buffer. n software, a stack buffer overflow or stack buffer overrun occurs when a program writes to a memory address on the program's call stack outside of the intended data structure, which is usually a fixed-length buffer. Stack buffer overflow can be caused deliberately as part of an attack known as stack smashing.The canonical method for exploiting a stack based buffer overflow is to overwrite the function return address with a pointer to attacker-controlled data (usually on the stack itself).

It causes some of that data to leak out into other buffers, which can corrupt or overwrite whatever data they were holding. When more data (than was originally allocated to be stored) gets placed by a program or system process, the extra data overflows. A buffer is a temporary area for data storage.In a buffer-overflow attack, the extra data sometimes holds specific instructions for actions intended by a hacker or malicious user for example, the data could trigger a response that damages files, changes data or unveils private information.Buffer overflow attacks are known to be the most common type of attacks that allow attackers to hijack a remote system by sending a specially crafted packet to a vulnerable network application running on it.Once an attacker grabs control of the victim program, she can invoke any operation to which the victim program’s effective user is entitled. A data structure that can affect the control flow of a program is called a control-sensitive data structure, examples of which include return address, function pointer, global offset table/import table, C++ virtual functions table pointer, etc.A control-hijacking attack overwrites some data structures in a victim program that affect its control flow, and eventually hijacks the control of the program and possibly the underlying system.
