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.

The remote MiracleLinux 3 host has packages installed that are affected by a vulnerability as referenced in the AXSA:2013-38:01 advisory.

    The Open IPMI project aims to develop an open code base to allow access to platform information using     Intelligent Platform Management Interface (IPMI). This package contains the tools of the OpenIPMI project.
    Security issues fixed with this release:
     CVE-2011-4339     ipmievd (aka the IPMI event daemon) in OpenIPMI, as used in the ipmitool package 1.8.11 in Red Hat     Enterprise Linux (RHEL) 6, Debian GNU/Linux, Fedora 16, and other products uses 0666 permissions for its     ipmievd.pid PID file, which allows local users to kill arbitrary processes by writing to this file.
    Fixed bugs:
     On non-Dell platforms, the ipmitool utility listed incomlete and misleading command usage. This has been     fixed.
     Disabled automatic bridging of SDR (Sensor Data Record) readings to IPMB to increase performance and show     sensor data correctly.
     Fixed exit code of 'ipmitool -o list' command: it now returns 0, as expected.
     Added the path to /sbin to lsmod and modprobe to prevent the init script from failing if PATH did not     point to /sbin.
     Added the -b, -B, -l and -T options in the ipmitool man page.
    Enhancements:
     Added some Dell-specific IPMI extension:
     vFlash: allows users to display information about extended SD cards.
     setled: allows users to display the backplane LED status.
     Improved error descriptions.
     Added support for new hardware.
     Updated documentation of the ipmitool delloem commands in the ipmitool manual page.

An updated ipmitool package that fixes one security issue is now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate 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 ipmitool package contains a command line utility for interfacing with devices that support the Intelligent Platform Management Interface (IPMI) specification. IPMI is an open standard for machine health, inventory, and remote power control.

The remote MiracleLinux 4 host has a package installed that is affected by a vulnerability as referenced in the AXSA:2012-21:01 advisory.

    This package contains a utility for interfacing with devices that support the Intelligent Platform     Management Interface specification.  IPMI is an open standard for machine health, inventory, and remote     power control.
    This utility can communicate with IPMI-enabled devices through either a kernel driver such as OpenIPMI or     over the RMCP LAN protocol defined in the IPMI specification.  IPMIv2 adds support for encrypted LAN     communications and remote Serial-over-LAN functionality.
    It provides commands for reading the Sensor Data Repository (SDR) and displaying sensor values, displaying     the contents of the System Event Log (SEL), printing Field Replaceable Unit (FRU) information, reading and     setting LAN configuration, and chassis power control.
    Security issues fixed with this release:
    CVE-2011-4339     ipmievd (aka the IPMI event daemon) in OpenIPMI, as used in the ipmitool package 1.8.11 in Red Hat     Enterprise Linux (RHEL) 6, Debian GNU/Linux, Fedora 16, and other products uses 0666 permissions for its     ipmievd.pid PID file, which allows local users to kill arbitrary processes by writing to this file.

This update fixes following security bug: CVE-2011-4339 - OpenIPMI:
IPMI event daemon creates PID file with world writeable permissions

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

A vulnerability has been discovered and corrected in ipmitool :

ipmievd as used in the ipmitool package uses 0666 permissions for its ipmievd.pid PID file, which allows local users to kill arbitrary processes by writing to this file (CVE-2011-4339).

In Mandriva the ipmievd daemon from the ipmitool package does not have an initscript to start and stop the service, however one could rather easily craft an initscript or start the service by other means rendering the system vulnerable to this issue.

The updated packages have been patched to correct this issue.
