RedHat: Low: shadow-utils security and bug fix update RHSA-2007:0276-02
Summary
Summary
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.
