NOTE: this is only relevant for PHP applications that accept untrusted input (instead of the system's php.ini file) for the parse_ini_string or parse_ini_file function, e.g., a web application for syntax validation of php.ini directives. (CVE-2017-11628) Impact This vulnerability allows unauthorized disclosure of information, unauthorized modification, and disruption of service. Security Advisory Status F5 Product Development has assigned ID 688625 (BIG-IP) to this vulnerability. Additionally, BIG-IP iHealth may list Heuristic H75543432 on the Diagnostics > Identified > Low page.

Security Advisory Recommended Actions If you are running a version listed in the Versions known to be vulnerable column, you can eliminate this vulnerability by upgrading to a version listed in the Versions known to be not vulnerable column. If the table lists only an older version than what you are currently running, or does not list a non-vulnerable version, then no upgrade candidate currently exists. Mitigation To mitigate this vulnerability, you should permit management access to F5 products only over a secure network and restrict command line access for affected systems to only trusted users. For more information, refer to K13309: Restricting access to the Configuration utility by source IP address (11.x - 13.x) and K13092: Overview of securing access to the BIG-IP system.
