The remote host is affected by the vulnerability described in GLSA-201606-07 (dhcpcd: Multiple vulnerabilities)

A heap overflow can be triggered via malformed DHCP responses in the print_option (via dhcp_envoption1) due to incorrect option length values.
These vulnerabilities could also allow remote attackers to trigger an invalid read/crash via malformed DHCP responses.
Impact :

Remote attackers could possibly execute arbitrary code with the privileges of the process or cause Denial of Service.
