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 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.
* 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.
