"Shellshock" and two memory corruption vulnerabilities. Bash is used by
IBM InfoSphere Guardium Database Activity Monitoring.
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 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-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-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.
