Summary

Six Bash vulnerabilities were disclosed in September 2014. This bulletin 
addresses the vulnerabilities that have been referred to as Bash Bug or 
Shellshock and two memory corruption vulnerabilities. Bash is used by IBM 
PureApplication System.

Vulnerability Details

CVE-ID: CVE-2014-6271

DESCRIPTION: GNU Bash could allow a remote attacker to execute arbitrary 
commands on the system, caused by an error when evaluating specially crafted 
environment variables passed to it by the Bash functionality. An attacker 
could exploit this vulnerability to write to files and execute arbitrary 
commands on the system.

CVSS Base Score: 10.0

CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/96153 for the 
current score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:L/Au:N/C:C/I:C/A:C)

CVE-ID: CVE-2014-7169

DESCRIPTION: GNU Bash could allow a remote attacker to execute arbitrary 
commands on the system, caused by an incomplete fix related to malformed 
function definitions in the values of environment variables. An attacker could
exploit this vulnerability using attack vectors involving the ForceCommand 
feature in OpenSSH sshd, and the mod_cgi and mod_cgid modules in the Apache 
HTTP Server to write to files and execute arbitrary commands on the system.

CVSS Base Score: 10.0

CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/96209 for the 
current score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:L/Au:N/C:C/I:C/A:C)

CVE-ID: CVE-2014-7186

DESCRIPTION: GNU Bash could allow a local attacker to execute arbitrary code 
on the system, caused by an out-of-bounds memory access while handling 
redir_stack. An attacker could exploit this vulnerability to execute arbitrary
code on the system or cause a denial of service.

CVSS Base Score: 4.6

CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/96237 for the 
current score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:L/AC:L/Au:N/C:P/I:P/A:P)

CVE-ID: CVE-2014-7187

DESCRIPTION: GNU Bash could allow a local attacker to execute arbitrary code 
on the system, caused by an off-by-one error when handling deeply nested flow
control constructs. An attacker could exploit this vulnerability to execute 
arbitrary code on the system or cause a denial of service.

CVSS Base Score: 4.6

CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/96238 for the 
current score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:L/AC:L/Au:N/C:P/I:P/A:P)

CVE-ID: CVE-2014-6277

DESCRIPTION: GNU Bash could allow a remote attacker to execute arbitrary code
on the system, caused by an incomplete fix related to the failure to properly
parse function definitions in the values of environment variables. An attacker
could exploit this vulnerability using attack vectors involving the 
ForceCommand feature in OpenSSH sshd, and the mod_cgi and mod_cgid modules in
the Apache HTTP Server to execute arbitrary code on the system or cause a 
denial of service.

CVSS Base Score: 10.0

CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/96686 for the 
current score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:L/Au:N/C:C/I:C/A:C)

CVE-ID: CVE-2014-6278

DESCRIPTION: GNU Bash could allow a remote attacker to execute arbitrary code
on the system, caused by an incomplete fix related to the parsing of user 
scripts. An attacker could exploit this vulnerability to execute arbitrary 
code on the system or cause a denial of service.

Affected Products and Versions

    IBM PureApplication System Version 1.0 and later fix packs

    IBM PureApplication System Version 1.1 and later fix packs

    IBM PureApplication System Version 2.0 and later fix packs

Remediation/Fixes

The solution is to apply the fixes with the following direction:

PureSystems Managers:

The PureSystems Managers on all IBM PureApplication System versions are 
affected. Upgrade the IBM PureApplication System to the following interim Fix
(iFix) levels:

    IBM PureApplication System Version 1.0 and later fix packs:

        Upgrade to IBM PureApplication System V1.0.0.4 iFix 9

    IBM PureApplication System Version 1.1 and later fix packs:

        Upgrade to IBM PureApplication System V1.1.0.4 iFix 4

    IBM PureApplication System Version 2.0 and later fix packs:

        Upgrade to IBM PureApplication System V2.0.0.0 iFix 2

Deployed Virtual Machines:

Deployed AIX virtual machines are not affected. Upgrade all deployed Red Hat 
Linux virtual machines by using an emergency fix (eFix) provided by IBM:

    Download the eFix from IBM Fix Central (see the following link):

    
http://www-933.ibm.com/support/fixcentral/swg/selectFixes?product=ibm/WebSphere/PureApplication+System&release=All&platform=All&function=fixId&fixids=RedHat_Image_Bash_Vulnerability&includeSupersedes=0

    Import the eFix into the IBM PureApplication System Emergency Fix catalog.

    Apply this Emergency Fix on each deployed Red Hat Linux virtual machine. 
    Bash is upgraded to version bash-4.1.2-15.e16_5.2.

Images:

For images, you can use the new default image, or you can extend and capture 
the existing image by using the following general procedure:

    Import the eFix into the IBM Workload Deployer Emergency Fix catalog.

    From the image catalog, select the image and click "Extend."

    After the image extend operation completes succcessfully, click Service 
from the deployed virtual machine.

    Apply this emergency fix.

    From the image catalog, capture the image.

Use this newly captured image for future deployment.
