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, 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 remote 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: 10
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/96237 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-2014-7187
DESCRIPTION: GNU Bash could allow a remote 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: 10
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/96238 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-2014-6277
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, 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

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.
CVSS Base Score: 10.0

Affected Products and Versions
IBM eDiscovery Identification and Collection 7.5, IBM eDiscovery
Identification and Collection 7.5.1, IBM Policy Assessment and Compliance 7.5,
IBM Policy Assessment and Compliance 7.5.1, IBM Unstructured Data
Identification and Mgmt 7.5, IBM Unstructured Data Identification and Mgmt
7.5.1
Note: These products are believed to be immune to most Shellshock attack
vectors. Currently, the only identified attack vector is DHCP, which if
utilized would be vulnerable to a compromised DHCP server. Where static IPs
are utilized, the DHCP attack vector is irrelevant.
