Description

From Red Hat Security Advisory 2007:0276 :

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.

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.
