CWE-440  (opens in a new tab)

How to fix?

Upgrade RHEL:7 glibc to version 0:2.17-55.el7_0.3 or higher.
This issue was patched in RHSA-2014:2023.

NVD Description

Note: Versions mentioned in the description apply only to the upstream glibc package and not the glibc package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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 "$((...))".
