Test ID:	1.3.6.1.4.1.25623.1.0.105372
Category:	F5 Local Security Checks
Title:	F5 BIG-IP - GNU C Library (glibc) vulnerability CVE-2014-7817
Summary:	The remote host is missing a security patch.
Description:	Summary: The remote host is missing a security patch. Vulnerability Insight: 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) Vulnerability 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. Solution: See the referenced vendor advisory for a solution. CVSS Score: 4.6 CVSS Vector: AV:L/AC:L/Au:N/C:P/I:P/A:P
