Description Andrej Nemec 2017-05-31 14:07:36 UTC 
In Open vSwitch while parsing an OpenFlow role status message, there is a call to the abort() function for undefined role status reasons in the function `ofp_print_role_status_message` in `lib/ofp-print.c` that may be leveraged toward a remote DoS attack by a malicious switch.
