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.
