7z AES encryption - IV randomness issues

[maenpaa24]

Hi! There was a bug in 7zip AES encryption which has been fixed recently. It has been reported here:

https://sourceforge.net/p/sevenzip/bugs/2176/

I haven't seen anything about it in the changelog. Is it fixed in the latest version? If so, could you add it to the changelog?

Thanks.

I am sorry that i am necromancing this thread. Are you aware of tools that exploit this error in 7Zip. I encrypted a file in 2017 but have forgotten the password.

Not really @freemin7, sorry.

Neither am I, sorry.
