SOL16010 - GNU C Library (glibc) vulnerability CVE-2014-7817

*These versions of BIG-IP, BIG-IQ, and Enterprise Manager have a vulnerable version of glibc code. However, the risk level for this vulnerability is considered LOW because F5 product development has verified that the vulnerable code is NOT used in a way that would make an exploit possible.

** These versions of the ARX system have a vulnerable version of glibc. However, F5 product development has reviewed the source code and confirmed that the vulnerable wordexp function is not used by the ARX system, so it is considered not vulnerable.

Note: As of February 17, 2015, AskF5 Security Advisory articles include the Severity value. Security Advisory articles published before this date do not list a Severity value.
