Question

Q:1. If we talk about control hijacking, which of the following is true ?
1.In Buffer overflow attacks, stack based attacks are more common than heap based attack.
2.Integer overflow attacks is not a type of control hijacking.
3.Format string vulnerabilities are used to prevent control hijacking.
4.All of the above

​

Answer 1

Answer:

The correct answer is 1

Explanation:

Stack-based buffer overflows are more common, and leverage stack memory that only exists during the execution time of a function. Heap-based attacks are harder to carry out and involve flooding the memory space allocated for a program beyond memory used for current runtime operations.

And Integer overflow attacks is a type of control hijacking.

Answer 2

1. In Buffer overflow attacks, stack-based attacks are more common than heap-based attacks the correct answer.

Explanation:

• Stack-primarily based buffer overflows are greater common, and leverage stack reminiscence that most effective exists all through the execution time of a feature.
• Heap-primarily based totally assaults are more difficult to perform and contain flooding the memory area allotted for an application past the reminiscence used for modern-day runtime operations.
• In general, stack overflows are greater usually exploited than heap overflows.
• This is due to the fact stacks comprise a chain of nested functions, every returning the cope with of the calling feature to which the stack ought to go back after the feature has completed running.

And Integer overflow assaults are a form of manage hijacking.
