The Orphanage / Re: I need a program called "F...

Last post by sudoku - April 24, 2024, 01:24:14 AM

Seems to be working ..... but
there also seems to be an endless loop, where the processing is already done -- but the program keeps "going to check whether all threads quit" etc... (endlessly see screenshot)



I stopped the program after 7 minutes while it was still stuck in the loop.

There also seems to be a couple of stalls along the way, where the program does not do anything for several seconds.

The Laboratory / x86 buffer overrun help

Last post by longfloat - April 24, 2024, 12:35:19 AM

Hey guys, im a cs undergraduate and we are learning about buffer overrun attacks. Im using a shellcode as shown below to overwrite some string literals of a printf in .rodata using mprotect() but i keep getting segmentation fault here:
Program received signal SIGSEGV, Segmentation fault.

[Deleted]

Im suspecting that this has smth to do with the stack pointers but i cant figure what it is yet. Can someone help?

Hi,

   Thank you.  I thought I had tried all of the switches,
but obviously not.

looks like in order to add other 46 threads, we must use the "Macro" things.
otherwise there are a lot of copy&past and replace

I can see clearly what your program is doing. If you ever get it finished and running very fast, it looks like it will be a very useful tool.

a1: yes, sha256sum + space + filePath.
a2: no.
  it's just testFiles.
  this app will find out:
    which files are in vs2k22community only.
    which files are in vs2k22buildtools only.
    which files are in vs2k22community&buildtools both

I used the findFile3sha256sum to create them

Looking at those files, I had thought that they must be some sort of checksum. 
Are you using that system of comparing checksums to check for corrupted files?
