- ---------------------------------------------------------------------
1. Summary:
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.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64

Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64

3. Problem description:
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.
