Description Andrej Nemec 2017-05-30 11:48:39 UTC

A vulnerability in openvswitch was found. 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`.
