Mandriva Linux Security Advisory 2014-232 - 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 expression 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.
