K16010 : GNU C Library (glibc) vulnerability CVE-2014-7817

Security Advisory Description

The wordexp function in GNU C Library (aka glibc) 2.21 does not enforce the WRDE_NOCMD flag, which allows context-dependent attackers to execute arbitrary commands, as demonstrated by input containing “$((...))”. (CVE-2014-7817)

Impact

An attacker with local access and knowledge of how to make the glibc function trigger an exploit may be able to run arbitrary 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.
