"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 Red
Hat 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. (CVE-2006-1174)

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."
