RHBA-2014:1217 - shadow-utils bug fix update

Synopsis

shadow-utils bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated shadow-utils packages that fix one bug are now available for Red Hat Enterprise Linux 5.

Description

The shadow-utils packages include programs for converting UNIX password files to the shadow password format, as well as utilities for managing user and group accounts.

This update fixes the following bug:

  • Due to the previously added support for the split groups, the newgrp command searched all groups on the system for a given GID. This behavior could cause high network traffic on systems pulling user and group information from a Lightweight Directory Access Protocol (LDAP) server. The underlying source code has been modified, so that this exhaustive search is not performed if the user is a member of a group whose name is specified with newgrp. (BZ#985475)

Users of shadow-utils are advised to upgrade to these updated packages, which fix this bug.

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/site/articles/11258
