The vulnerability is caused due to certain shell meta-characters not being stripped or escaped when processing responses from a DHCP server. This can be exploited to inject and execute arbitrary shell commands via e.g. a specially crafted "hostname" response. The vulnerability is reported in versions prior to 5.2.12. SOLUTION: Update to version 5.2.12.
