Subject: Security ERRATA Low: OpenIPMI on SL5.x i386/x86_64
Newsgroups: gmane.linux.scientific.errata
Date: Wednesday 16th January 2013 22:10:12 UTC (over 3 years ago)
Synopsis:          Low: OpenIPMI security, bug fix, and enhancement update
Issue Date:        2013-01-08
CVE Numbers:       CVE-2011-4339
--

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 Scientific 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.

* 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.

* 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.

* 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.

* 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.

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.
