shadow security update

CentOS Errata and Security Advisory CESA-2007:0276

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.
