WebBuffers are widespread in operating system(OS) code, so it is possible to make attacks that perform privilege escalationand gain unlimited access to the computer's resources. The famed Morris wormin 1988 used this as one of its attack techniques. WebOverwriting values of the IP (Instruction Pointer), BP (Base Pointer) and other registers causes exceptions, segmentation faults, and other errors to occur. Usually these errors …

WebWe present eight tests to verify the effectiveness of IMPULP, including five memory protection function tests, a test to defense typical buffer overflow, a test to defense famous memory leakage attack named Heartbleed, and a test for security benchmark. We execute the SPEC CPU2006 benchmark programs to evaluate the efficiency of IMPULP. Buffer overflow attacks come in different forms, and employ different tactics to target vulnerable applications. The two most common attack tactics are: Stack overflow attack: A stack-based buffer overflow occurs when a program writes more data to a buffer located on the stack than what is actually … See more A buffer overflow, just as the name implies, is an anomaly where a computer program, while writing data to a buffer, overruns it’s capacity or the buffer’s boundary and then … See more The buffer overflow problem is one of the oldest and most common problems in software development dating back to the introduction of … See more The main reason buffer overflow occurs is because software developers fail to perform bounds checking.
