RESOLUTION
HP has provided the following instructions to resolve these vulnerabilities.
Follow these steps to update the HP Insight Control for Linux Central
Management Server Pre-boot Execution Environment:
NOTE: The following procedure updates the bash shell on the Linux Pre-boot
Execution Environment on HP Insight Control for Linux Central Management
Server. Please update the bash shell version on the Linux operating system
running on the Central Management server that is hosting HP Insight Control
for Linux.
1. On the Production RHEL 6.2 OS:
a. Prepare temporary directory for Bash update software:
# mkdir -p $HOME/tmp/bash
# cd $HOME/tmp/bash
# pwd
<home directory>/tmp/bash
b. Download the file 'bash-4.1.2-15.el6_4.2.i686.rpm' for Insight Control for
Linux Red Hat 6.2 i386 from https://rhn.redhat.com/errata/RHSA-2014-1311.html
Non-HP site to the temporary directory '$HOME/tmp/bash'.
c. Extract the Bash update software package.
# rpm2cpio bash-4.1.2-15.el6_4.2.i686.rpm| cpio -idmv
d. Verify the version of the Bash update software:
# ./bin/bash --version
GNU bash, version 4.1.2(1)-release (i686-redhat-linux-gnu)
e. Verify version dependencies:
# ldd ./bin/bash
linux-gate.so.1 => (0x008a7000)
libtinfo.so.5 => /lib/libtinfo.so.5 (0x00459000)
libdl.so.2 => /lib/libdl.so.2 (0x002c0000)
libc.so.6 => /lib/libc.so.6 (0x0012e000)
/lib/ld-linux.so.2 (0x00108000)
f. Create archive file from '/lib' to copy and install on the Insight Control
for Linux Central Management Server Pre-boot Execution Environment system:
# mkdir $HOME/tmp/lib
# cd /lib
# cp * $HOME/tmp/lib
# cd $HOME/tmp
# pwd
<home directory>/tmp
# tar cvf bash_lib.tar *
2. Download the new archive file '$HOME/tmp/bash_lib.tar' from the Production
RHEL 6.2 OS system to the Insight Control for Linux Central Management Server
Pre-boot Execution Environment system.
3. On the HP Insight Control for Linux Central Managment Server Pre-boot
Execution Environment system:
a. Create a temporary folder for the toolkit and copy the toolkit there :
# mkdir -p $HOME/tmp/temp-toolkit
# cp /usr/share/systemimager/boot/i386/standard/toolkit.tar.gz
$HOME/tmp/temp-toolkit
b. Extract the file 'toolkit.tar.gz' into the temporary folder:
# cd $HOME/tmp/temp-toolkit
# tar zxvf toolkit.tar.gz
# mv $HOME/tmp/temp-toolkit/toolkit.tar.gz /tmp
c. Verify the version of the toolkit Bash:
# $HOME/tmp/temp-toolkit/bin/bash --version
GNU bash, version 3.2.0(1)-release (i386-pc-linux-gnu) Copyright (C) 2005 Free
Software Foundation, Inc.
d. Verify dependencies versions:
# ldd $HOME/tmp/temp-toolkit/bin/bash
linux-gate.so.1 => (0xffffe000)
libtermcap.so.2 => /lib/libtermcap.so.2 (0xf7f8c000)
libdl.so.2 => /lib/libdl.so.2 (0x008bf000)
libc.so.6 => /lib/libc.so.6 (0x00777000)
/lib/ld-linux.so.2 (0x00755000)
e. Extract the archive 'bash_lib.tar' to directory '$HOME/tmp/bash_lib' . Then
copy the bash binary and the library files to their respective locations:
# tar xvf $HOME/tmp/bash_lib
# cp $HOME/tmp/bash_lib/bash/bash $HOME/tmp/temp-toolkit/bin
# cp $HOME/tmp/bash_lib/lib/* $HOME/tmp/temp-toolkit/lib
f. Create the updated toolkit gzipped archive file and place in
/usr/share/systemimager/boot/i386/standard
# tar czvf toolkit.tar.gz *
# cp toolkit.tar.gz /usr/share/systemimager/boot/i386/standard
