Note:- Take only idea of reason don’t copy paste

 it otherwise you will face UFM.

Q1. Which of the following programming

languages have common buffer overflow problem

in the development of applications?

1. C, Ruby

2. C, C++

3. Python, Ruby

4. C, Python

Reason:- The problem of buffer overflows is

common in the C and C++ languages because

they expose low level representational details of

buffers as containers for data types.

Q2. Which type of buffer overflows are common

among attackers?

1. Memory-based

2. Queue-based

3. Stack-based

4. Heap-based

Reason:- Stack-based buffer overflows, which 

are more common among attackers, exploit 

applications and programs by using what is 

known as a stack: memory space used to store

user input.

Q3. In ___________ attack, malicious code is 

pushed into _______.

1. buffer-overflow, stack

2. buffer-overflow,queue

3. buffer-overflow, memory-card

4. buffer-overflow,external drive

Reason:- Malicious code can be pushed into the

stack during the buffer-overflow attack. The 

overflow can be used to overwrite the return 

pointer so that the control-flow switches to the

malicious code.

Q4. In case of integer overflow, Which of the 

following option/s is/are true?

1. It is a result of an attempt to store a value greater than the maximum value an integer can store

2. Integer overflow can compromise a program's reliability and security

3. Both A and B

4. None of the above

Reason:- An integer overflow is a type of an 

arithmetic overflow error when the result of an

integer operation does not fit within the 

allocated memory space. Instead of an error in

the program, it usually causes the result to be 

unexpected. Integer overflows have been listed

as the number 8 most dangerous software error

in the most recent CWE 2019 list

Q5. A string which contains ___________ 

parameter/s, is called ______ string.

1. Format, text

2. Text, format

3. text and format, format

4. None of the above

Reason:- The Format String is the argument of 

the Format Function and is an ASCII Z string 

which contains text and format parameters, like:

printf (“The magic number is: %d\n”, 1911);
