Security Bulletin

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 
Proventia Network Enterprise Scanner.

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-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 
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.

CVSS Base Score: 10.0

CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/96687 for the 
current score
