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: 10.0CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/96153 for the current scoreCVSS Environmental Score*: UndefinedCVSS 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.

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: 4.6CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/96237 for the current scoreCVSS Environmental Score*: UndefinedCVSS 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
