When the candidate has been publicized, the details for this candidate will be provided. CVE-2016-5095 ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when announcing a new security problem. When the candidate has been publicized, the details for this candidate will be provided. Impact Although BIG-IP and BIG-IQ software contains the vulnerable code, BIG-IP and BIG-IQ do not use the vulnerable code in a way that exposes the vulnerability in a standard default configuration. When exploited, the PHP module may encounter an out-of-memory error that affects the Configuration utility. Security Issue Status F5 Product Development has assigned ID 599285 (BIG-IP) and ID 599562 (BIG-IQ and iWorkflow) to this vulnerability. To determine if your release is known to be vulnerable, the components or features that are affected by the vulnerability, and for information about releases or hotfixes that address the vulnerability, refer to the following table: Product Versions known to be vulnerable Versions known to be not vulnerable Severity Vulnerable component or feature BIG-IP LTM 12.0.0 - 12.1.0 11.4.0 - 11.4.1 Low Configuration utility 11.5.0 - 11.6.1 11.2.1 10.2.1 - 10.2.4 BIG-IP AAM 12.0.0 - 12.1.0 11.4.0 - 11.4.1 Low Configuration utility 11.5.0 - 11.6.1 BIG-IP AFM 12.0.0 - 12.1.0 11.4.0 - 11.4.1 Low Configuration utility 11.5.0 - 11.6.1 BIG-IP Analytics 12.0.0 - 12.1.0 11.4.0 - 11.4.1 Low Configuration utility 11.5.0 - 11.6.1 11.2.1 BIG-IP APM 12.0.0 - 12.1.0 11.4.0 - 11.4.1 Low Configuration utility 11.5.0 - 11.6.1 11.2.1 10.2.1 - 10.2.4 BIG-IP ASM 12.0.0 - 12.1.0 11.4.0 - 11.4.1 Low Configuration utility 11.5.0 - 11.6.1 11.2.1 10.2.1 - 10.2.4 BIG-IP DNS 12.0.0 - 12.1.0 None Low Configuration utility BIG-IP Edge Gateway None 11.2.1 Not vulnerable None 10.2.1 - 10.2.4 BIG-IP GTM 11.5.0 - 11.6.1 11.4.0 - 11.4.1 Low Configuration utility 11.2.1 10.2.1 - 10.2.4 BIG-IP Link Controller 12.0.0 - 12.1.0 11.4.0 - 11.4.1 Low Configuration utility 11.5.0 - 11.6.1 11.2.1 10.2.1 - 10.2.4 BIG-IP PEM 12.0.0 - 12.1.0 11.4.0 - 11.4.1 Low Configuration utility 11.5.0 - 11.6.1 BIG-IP PSM None 11.4.0 - 11.4.1 Not vulnerable None 10.2.1 - 10.2.4 BIG-IP WebAccelerator None 11.2.1 Not vulnerable None 10.2.1 - 10.2.4 BIG-IP WOM None 11.2.1 Not vulnerable None 10.2.1 - 10.2.4 ARX None 6.2.0 - 6.4.0 Not vulnerable None Enterprise Manager None 3.1.1 Not vulnerable None FirePass None 7.0.0 Not vulnerable None BIG-IQ Cloud 4.4.0 - 4.5.0 4.0.0 - 4.3.0 Low Configuration utility BIG-IQ Device 4.4.0 - 4.5.0 4.2.0 - 4.3.0 Low Configuration utility BIG-IQ Security 4.4.0 - 4.5.0 4.0.0 - 4.3.0 Low Configuration utility BIG-IQ ADC 4.5.0 None Low Configuration utility BIG-IQ Centralized Management 5.0.0 None Low Configuration utility 4.6.0 BIG-IQ Cloud and Orchestration 1.0.0 None Low Configuration utility F5 iWorkflow 2.0.0 None Low Configuration utility LineRate None 2.5.0 - 2.6.1 Not vulnerable None F5 MobileSafe None 1.0.0 Not vulnerable None F5 WebSafe 1.0.0 None Low Configuration utility Traffix SDC None 5.0.0 Not vulnerable None 4.0.0 - 4.4.0 Vulnerability 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. To mitigate this vulnerability, you should ensure that the PHP memory limit is not modified and remains in its default value. F5 does not recommend modifying the default value for PHP memory limit.

(CVE-2015-8873) Impact An authenticated attacker may be able to upload and execute arbitrary PHP code and cause a denial-of-service (DoS) attack. In default configurations, the BIG-IP system protects against this vulnerability by limiting the available memory for PHP. Security Issue Status F5 Product Development has assigned ID 606704 (BIG-IP) to this vulnerability, and has evaluated the currently supported releases for potential vulnerability. To determine if your release is known to be vulnerable, the components or features that are affected by the vulnerability, and for information about releases or hotfixes that address the vulnerability, refer to the following table: Product Versions known to be vulnerable Versions known to be not vulnerable Severity Vulnerable component or feature BIG-IP LTM 12.0.0 12.1.0 Low PHP 11.4.0 - 11.6.0 11.6.1 11.2.1 11.5.4 10.2.1 - 10.2.4 BIG-IP AAM 12.0.0 12.1.0 Low PHP 11.4.0 - 11.6.0 11.6.1 11.2.1 11.5.4 BIG-IP AFM 12.0.0 12.1.0 Low PHP 11.4.0 - 11.6.0 11.6.1 11.5.4 BIG-IP Analytics 12.0.0 12.1.0 Low PHP 11.4.0 - 11.6.0 11.6.1 11.2.1 11.5.4 BIG-IP APM 12.0.0 12.1.0 Low PHP 11.4.0 - 11.6.0 11.6.1 11.2.1 11.5.4 10.2.1 - 10.2.4 BIG-IP ASM 12.0.0 12.1.0 Low PHP 11.4.0 - 11.6.0 11.6.1 11.2.1 11.5.4 10.2.1 - 10.2.4 BIG-IP DNS 12.0.0 12.1.0 Low PHP BIG-IP Edge Gateway 11.2.1 None Low PHP 10.2.1 - 10.2.4 BIG-IP GTM 11.4.0 - 11.6.0 11.6.1 Low PHP 11.2.1 11.5.4 10.2.1 - 10.2.4 BIG-IP Link Controller 12.0.0 12.1.0 Low PHP 11.4.0 - 11.6.0 11.6.1 11.2.1 11.5.4 10.2.1 - 10.2.4 BIG-IP PEM 12.0.0 12.1.0 Low PHP 11.4.0 - 11.6.0 11.6.1 11.5.4 BIG-IP PSM 11.4.0 - 11.4.1 None Low PHP 10.2.1 - 10.2.4 BIG-IP WebAccelerator 11.2.1 None Low PHP 10.2.1 - 10.2.4 BIG-IP WOM 11.2.1 None Low PHP 10.2.1 - 10.2.4 ARX None 6.2.0 - 6.4.0 Not vulnerable None Enterprise Manager 3.1.1 None Low PHP FirePass None 7.0.0 Not vulnerable None BIG-IQ Cloud 4.0.0 - 4.5.0 None Low PHP BIG-IQ Device 4.2.0 - 4.5.0 None Low PHP BIG-IQ Security 4.0.0 - 4.5.0 None Low PHP BIG-IQ ADC 4.5.0 None Low PHP BIG-IQ Centralized Management 5.0.0 None Low PHP 4.6.0 BIG-IQ Cloud and Orchestration 1.0.0 None Low PHP F5 iWorkflow 2.0.0 None Low PHP LineRate None 2.5.0 - 2.6.1 Not vulnerable None F5 MobileSafe ** ** ** ** F5 WebSafe ** ** ** ** Traffix SDC None 5.0.0 Not vulnerable None 4.0.0 - 4.4.0 ** Confirmation of vulnerability or non-vulnerability is not presently available. F5 is still researching the issue for the products indicated, and will update this article with the most current information as soon as it has been confirmed. F5 Technical Support does not have any additional information on this issue. Vulnerability 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. To mitigate this vulnerability, you should permit management access to F5 products only over a secure network and limit shell access to only trusted users.
