Medium Nessus Plugin ID 79612
SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionUpdated 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).
SolutionUpdate the affected packages.
