Summary
Details
In Open vSwitch (OvS) 2.5.0, 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.
Severity
