A remote attacker may be able to use this flaw to execute arbitrary code. (CVE-2015-0235) Impact A remote attacker may be able to execute arbitrary code. Status F5 Product Development has assigned ID 503237 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 Vulnerable component or feature BIG-IP LTM 11.0.0 - 11.6.0* 10.1.0 - 10.2.4* None glibc BIG-IP AAM 11.4.0 - 11.6.0* None glibc BIG-IP AFM 11.3.0 - 11.6.0* None glibc BIG-IP Analytics 11.0.0 - 11.6.0* None glibc BIG-IP APM 11.0.0 - 11.6.0* 10.1.0 - 10.2.4* None glibc BIG-IP ASM 11.0.0 - 11.6.0* 10.1.0 - 10.2.4* None glibc BIG-IP Edge Gateway 11.0.0 - 11.3.0* 10.1.0 - 10.2.4* None glibc BIG-IP GTM 11.0.0 - 11.6.0* 10.1.0 - 10.2.4* None glibc BIG-IP Link Controller 11.0.0 - 11.6.0* 10.1.0 - 10.2.4* None glibc BIG-IP PEM 11.3.0 - 11.6.0* None glibc BIG-IP PSM 11.0.0 - 11.4.1* 10.1.0 - 10.2.4* None glibc BIG-IP WebAccelerator 11.0.0 - 11.3.0* 10.1.0 - 10.2.4* None glibc BIG-IP WOM 11.0.0 - 11.3.0* 10.1.0 - 10.2.4* None glibc ARX 6.0.0 - 6.4.0* None glibc Enterprise Manager 3.0.0 - 3.1.1* 2.1.0 - 2.3.0* None glibc BIG-IQ Cloud 4.0.0 - 4.5.0* None glibc BIG-IQ Device 4.2.0 - 4.5.0* None glibc BIG-IQ Security 4.0.0 - 4.5.0* None glibc *F5 has determined that these products contain vulnerable versions of glibc, and the vulnerable function is used in the product; however, at this time F5 does not have evidence of any remote exploit vectors for this vulnerability. Recommended Action If the previous table lists a version in the Versions known to be not vulnerable column, you can eliminate this vulnerability by upgrading to the listed version. If the listed version is older than the version you are currently running, or if the table does not list any version in the column, then no upgrade candidate currently exists. F5 is working to provide a patch for this issue, and will update this article as soon as a patch becomes available. F5 is responding to this vulnerability as determined by the parameters defined in SOL4602: Overview of the F5 security vulnerability response policy. To mitigate this vulnerability, you should only permit access to F5 products over a secure network and limit login access to trusted users. For additional information, refer to SOL13092: Overview of securing access to the BIG-IP system. For information about using the BIG-IP ASM system and iRules to mitigate various GHOST exploits, refer to the GHOST Vulnerability (CVE-2015-0235) DevCentral article.
