WebTo prevent such attacks, Data Execution Prevention was introduced. With this feature enabled, it would become challenging for the hacker to overflow the buffer and perform malicious attacks like the famous Ret2libc attack, in which the attack overflows the buffer to point the instruction pointer (IP) to access dangerous locations in the memory. WebData Execution Prevention (DEP) is a security feature in modern operating systems, including Windows, that aims to prevent buffer overflow attacks by preventing the execution of code from memory locations that should only contain data. 2):-

WebIn information securityand programming, a buffer overflow, or buffer overrun, is an anomalywhereby a program, while writing datato a buffer, overruns the buffer's boundary and overwrites adjacent memorylocations. Buffers are areas of memory set aside to hold data, often while moving it from one section of a program to another, or between programs.
