Stack-based buffer overflows: This is the most common form of buffer overflow attack. The stack-based approach occurs when an attacker sends data containing malicious code to an application, which stores the data in a stack buffer. This overwrites the data on the stack, including its return ...
and software exceptions. It thus prevents an attacker from being able to make use of the SEH overwrite exploitation technique. At a functional level, an SEH overwrite is achieved using a stack-based buffer overflow to overwrite an exception registration record, stored on a thread’s stack. ...
A stack buffer overflow is a continuous memory space used for data organization associated with function calls, parameters, local variables, and management information. It’s empty until the target program requires user input, such as a password or username. The program then writes a return ...
Stack-based buffer overflow or stack buffer overrun attack The stack holds data in a last-in, first-out structure. It is a continuous space in memory used to organize data associated with function calls, including function parameters, function local variables and management information, such as fr...
Here is a very simple example of a C program that is vulnerable to a stack overflow: main(intargc,char*argv[]) { func(argv[1]); }voidfunc(char*v){charbuffer[10]; strcpy(buffer, v); } Thestrcpyfunction in the above example copies the command argument into the destination buffer varia...
Buffer overflows are one of the worst bugs that can be exploited by an attacker mostly because it is very hard to find and fix, especially if the software consists of millions of lines of code. Even the fixes for these bugs are quite complicated and error-prone. That is why it is real...
