Description Andrej Nemec 2017-05-31 14:04:04 UTC 
In Open vSwitch a malformed IP packet can cause the switch to read past the end of the packet buffer due to an unsigned integer underflow in `lib/flow.c` in the function `miniflow_extract`, permitting remote bypass of the access control list enforced by the switch.
