Name of the Vulnerable Software and Affected Versions Open vSwitch version 2.5.0

Description A malformed IP packet can cause the switch to read past the end of the packet buffer due to an unsigned integer underflow in the function miniflow extract in lib/flow.c, permitting remote bypass of the access control list enforced by the switch.

Recommendations For Open vSwitch version 2.5.0, consider disabling the miniflow extract function in lib/flow.c as a temporary workaround until a patch is available. Restrict access to the switch to minimize the risk of exploitation.
