CVE-2023-4641 – Shadow-utils: possible password leak during passwd(1) change

https://notcve.org/view.php?id=CVE-2023-4641

A flaw was found in shadow-utils. When asking for a new password, shadow-utils asks the password twice. If the password fails on the second attempt, shadow-utils fails in cleaning the buffer used to store the first entry. This may allow an attacker with enough access to retrieve the password from the memory.
