DESCRIPTION:
A security issue has been reported in the Config::IniFiles module for
Perl, which can be exploited by malicious, local users to perform
certain actions with escalated privileges.

The security issue is caused due to the application using a temporary
file in an insecure manner, which can be exploited to e.g. overwrite
arbitrary files via symlink attacks.

The security issue is reported in versions prior to 2.71.
