CVE-2023-4641 Open this link in a new tabHow to fix?
There is no fixed version for Debian:11 shadow.
NVD Description
Note: Versions mentioned in the description apply only to the upstream shadow package and not the shadow package as distributed by Debian.
See How to fix? for Debian:11 relevant fixed versions and status.
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.
