Low: shadow-utils security and bug fix update

An updated shadow-utils package that fixes a security issue and several
bugs is 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.

* chage.1 and chage -l gave incorrect information about sp_inact.

All users of shadow-utils are advised to upgrade to this updated
package, which contains backported patches to resolve these issues.
