Opened: Aug 03, 2016 Severity: 1-Blocking
Two client side DHCP packets with giaddr field set, one with source port 67 and another client side packet with source port 68 (not conforming to RFC since giaddr set DHCP packet (from relay agent) should use 67 as source port per RFC), tmm will crash during err message logging.
Traffic disrupted while tmm restarts.
1) Two client side DHCP packets arrive one after another. 2) Both DHCP packets have giaddr fields set 3) One packet uses 67 as source port, the other uses 68
The conditions that cause the crash should not happen in a normal network setup. A DHCP relay agent should only use 67 as source port.
None
