How to fix?

Upgrade Debian:8 shadow to version 1:4.0.15-10 or higher.

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:8 relevant fixed versions and status.

useradd in shadow-utils before 4.0.3, and possibly other versions before 4.0.8, does not provide a required argument to the open function when creating a new user mailbox, which causes the mailbox to be created with unpredictable permissions and possibly allows attackers to read or modify the mailbox.
