Detail
| Problem Description: Updated shadow-utils packages that fix a security issue and various bugs are 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 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - 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. * 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. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command: up2date For information on how to install packages manually, refer to the following Web page for the System Administration or Customization guide specific to your system: http://www.redhat.com/docs/manuals/enterprise/ 5. Bug IDs fixed (http://bugzilla.redhat.com/): 176951 - shadow-utils-debuginfo is empty 177017 - faillog doesn't handle large UIDs well 188263 - typo in /etc/login.defs 193053 - CVE-2006-1174 shadow-utils mailbox creation race condition |
