CVE-2017-9214
In Open vSwitch (OvS) 2.7.0, while parsing an OFPT_QUEUE_GET_CONFIG_REPLY type OFP 1.0 message, there is a buffer over-read that is caused by an unsigned integer underflow in the function `ofputil_pull_queue_get_config_reply10` in `lib/ofp-util.c`.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.89%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
