For more information, please see: http://ftp.gnu.org/gnu/bash/bash-4.3-patches/bash43-027 ; https://support.broadcom.com/web/ecx/support-content-notification/-/external/content/SecurityAdvisories/0/23467 ; https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20140926-bash ; https://www.ibm.com/support/pages/security-bulletin-update-vulnerabilities-bash-affect-aix-toolbox-linux-applications-cve-2014-6271-cve-2014-6277-cve-2014-6278-cve-2014-7169-cve-2014-7186-and-cve-2014-7187 ; https://nvd.nist.gov/vuln/detail/CVE-2014-6278
Description
GNU Bash through 4.3 bash43-026 does not properly parse function definitions in the values of environment variables, which allows remote attackers to execute arbitrary commands via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271, CVE-2014-7169, and CVE-2014-6277.
