RHEL 4 : shadow-utils (RHSA-2007:0276)

critical Nessus Plugin ID 25144

Synopsis

The remote Red Hat host is missing a security update for shadow-utils.

Description

The remote Redhat Enterprise Linux 4 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2007:0276 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL shadow-utils package based on the guidance in RHSA-2007:0276.
