FreeBSD : dhcpcd -- multiple vulnerabilities (df587aa2-b5a5-11e5-9728-002590263bf5)

Critical Nessus Plugin ID 87791


The remote FreeBSD host is missing a security-related update.


Nico Golde reports :

heap overflow via malformed dhcp responses later in print_option (via dhcp_envoption1) due to incorrect option length values. Exploitation is non-trivial, but I'd love to be proven wrong.

invalid read/crash via malformed dhcp responses. not exploitable beyond DoS as far as I can judge.


Update the affected package.
