Updated shadow-utils packages that fix a security issue and various bugs
are now available.
This update has been rated as having low security impact by the CentOS
Security Response Team.
The shadow-utils package includes the necessary programs for converting
UNIX password files to the shadow password format, as well as programs for
managing user and group accounts.
A flaw was found in the useradd tool in shadow-utils. A new user's
mailbox, when created, could have random permissions for a short period.
This could allow a local attacker to read or modify the mailbox.
This update also fixes the following bugs:
* shadow-utils debuginfo package was empty.
* faillog was unusable on 64-bit systems. It checked every UID from 0 to
the max UID, which was an excessively large number on 64-bit systems.
* typo bug in login.defs file
All users of shadow-utils are advised to upgrade to these updated packages,
which contain backported patches to resolve these issues.
