Lecture 06 - Buffer Overflow

Question 1

Buffer Overflow

Answer 1

Occurs when data volume exceeds memory buffer capacity

Question 2

Corruption of data

Answer 2

Result of buffer overflow causing data integrity issues

Question 3

Memory Access Violations

Answer 3

Potential consequence of buffer overflow leading to unauthorized memory access

Question 4

Stack Based Buffer Overflow

Answer 4

Type of Buffer Overflow attack leveraging stack memory during function execution

Question 5

Heap-based attacks

Answer 5

Attacks flooding memory space allocated for a program beyond runtime operations

Question 6

Program Memory Layout

Answer 6

Memory segmentation in a typical C program including text, data, heap, and stack segments

Question 7

Address space randomization (ASLR)

Answer 7

Security measure randomizing address space locations to prevent attacks

Question 8

Data execution prevention

Answer 8

Flags memory areas as executable or non-executable to prevent code execution

Question 9

Structured exception handler overwrite protection (SEHOP)

Answer 9

Prevents attackers from exploiting Structured Exception Handling overwrite

Question 10
