Summary |
---|
Six Bash vulnerabilities were disclosed in September 2014. These vulnerabilities have been referred to as “Bash Bug” or “Shellshock”. Bash is used by SAN Volume Controller and Storwize Family (including the IBM Flex System V7000).
Vulnerability Details |
---|
The following vulnerabilities are only exploitable by users who
already have authenticated access to the system.
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 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: 10.0
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 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: 10.0
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 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.
