RHEL 5 : OpenIPMI (RHSA-2013:0123)

low Nessus Plugin ID 63406

Language:

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated OpenIPMI packages that fix one security issue, multiple bugs, and add one enhancement are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The OpenIPMI packages provide command line tools and utilities to access platform information using Intelligent Platform Management Interface (IPMI). System administrators can use OpenIPMI to manage systems and to perform system health monitoring.

It was discovered that the IPMI event daemon (ipmievd) created its process ID (PID) file with world-writable permissions. A local user could use this flaw to make the ipmievd init script kill an arbitrary process when the ipmievd daemon is stopped or restarted.
(CVE-2011-4339)

Note: This issue did not affect the default configuration of OpenIPMI as shipped with Red Hat Enterprise Linux 5.

This update also fixes the following bugs :

* Prior to this update, the ipmitool utility first checked the IPMI hardware for Dell IPMI extensions and listed only supported commands when printing command usage like the option 'ipmtool delloem help'. On a non-Dell platform, the usage text was incomplete and misleading.
This update lists all Dell OEM extensions in usage texts on all platforms, which allows users to check for command line arguments on non-Dell hardware. (BZ#658762)

* Prior to this update, the ipmitool utility tried to retrieve the Sensor Data Records (SDR) from the IPMI bus instead of the Baseboard Management Controller (BMC) bus when IPMI-enabled devices reported SDR under a different owner than the BMC. As a consequence, the timeout setting for the SDR read attempt could significantly decrease the performance and no sensor data was shown. This update modifies ipmitool to read these SDR records from the BMC and shows the correct sensor data on these platforms. (BZ#671059, BZ#749796)

* Prior to this update, the exit code of the 'ipmitool -o list' option was not set correctly. As a consequence, 'ipmitool -o list' always returned the value 1 instead of the expected value 0. This update modifies the underlying code to return the value 0 as expected.
(BZ#740780)

* Prior to this update, the 'ipmi' service init script did not specify the full path to the '/sbin/lsmod' and '/sbin/modprobe' system utilities. As a consequence, the init script failed when it was executed if PATH did not point to /sbin, for example, when running 'sudo /etc/init.d/ipmi'. This update modifies the init script so that it now contains the full path to lsmod and modrpobe. Now, it can be executed with sudo. (BZ#829705)

* Prior to this update, the ipmitool man page did not list the '-b', '-B', '-l' and '-T' options. In this update, these options are documented in the ipmitool man page. (BZ#846596)

This update also adds the following enhancement :

* Updates to the Dell-specific IPMI extension: A new vFlash command, which allows users to display information about extended SD cards; a new setled command, which allows users to display the backplane LED status; improved error descriptions; added support for new hardware;
and updated documentation of the ipmitool delloem commands in the ipmitool manual page. (BZ#797050)

All users of OpenIPMI are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add this enhancement.

Solution

Update the affected packages.
