DescriptionThe fr_dhcp_decode function in lib/dhcp.c in FreeRADIUS 2.1.9, in certain non-default builds, does not properly handle the DHCP Relay Agent Information option, which allows remote attackers to cause a denial of service (infinite loop and daemon outage) via a packet that has more than one sub-option. NOTE: some of these details are obtained from third party information.
