CVE-2014-7817  (opens in a new tab)
CWE-20  (opens in a new tab)

How to fix?

Upgrade Debian:10 glibc to version 2.19-14 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream glibc package and not the glibc package as distributed by Debian. See How to fix? for Debian:10 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 "$((...))".
