Synopsis

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.
