Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

Description :

Updated glibc package fixes security vulnerability :

The function wordexp\(\) fails to properly handle the WRDE_NOCMD flag
when processing arithmetic inputs in the form of $((... ``)) where ...
can be anything valid. The backticks in the arithmetic epxression are
evaluated by in a shell even if WRDE_NOCMD forbade command
substitution. This allows an attacker to attempt to pass dangerous
commands via constructs of the above form, and bypass the WRDE_NOCMD
flag. This update fixes the issue (CVE-2014-7817).
