I would like to know in what manner dangling pointers affect the
security of a application developed using C++.What are the loopholes
that are created by dangling pointers and how they could be exploited
by hackers?.

Hello everybody
in a quiz I had a question about dangling pointer:
"What a dangling pointer is and the danger of using it"
My answer was:
"dangling pointer is a pointer that points to some area of ram that's
not reserved by the program. Accessing memory through such pointer is
likely to result in core dump (memory access violation)"

My experience has always been that you're SOL when trying to safely
detect and stop references to dangling memory (non-null pointers to
free'ed blocks) at runtime (C99, Linux).
Maybe somebody clever has worked this out, though?
(Apologies to those who find the question off topic for CUP or CLC)

1.when referenced pointer is not active then it is called dangling pointer.
is this correct ?
2.the pointer which does not point to anything is called null pointer.
is NULL macro is a value for null pointer?
3.then what is void pointer?

I saw this on Slashdot and thought it was interesting. There's no released POC as far as I know, but i was curious. How do you guys find things like dangling pointers? (Blackbox testing, trusting the compiler, etc...?)

Hi All,
I have a doubt on undrestanding Dangling pointers.Below I mentioned sample code. please let me know, my view on Dangling pointers is correct or not?
main( )
{
char *a,*b,*c;
a = (char *)malloc(40);
b = a;
c = b;
free(a);

I read that you should assign null (0) to all pointers that you call
delete on.
Does that mean:
*p=0(set the value pointed to to 0).
or
p=0(set the address held to zero).

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
