Overview
Affected versions of this package are vulnerable to Improper Neutralization via the BOOTP file field being written to the lease file without escaping embedded double-quotes. An attacker can execute arbitrary code as root by injecting malicious dhclient.conf directives through a rogue DHCP server, which are then evaluated when the lease file is re-parsed by dhclient.
