high complexity
openvswitch CWE-772
5.9
2017-05-29 CVE-2017-9265 Out-of-bounds Read vulnerability in Openvswitch 2.7.0
In Open vSwitch (OvS) v2.7.0, there is a buffer over-read while parsing the group mod OpenFlow message sent from the controller in `lib/ofp-util.c` in the function `ofputil_pull_ofp15_group_mod`.

9.8
2017-05-29 CVE-2017-9264 Out-of-bounds Read vulnerability in Openvswitch 2.6.1
In lib/conntrack.c in the firewall implementation in Open vSwitch (OvS) 2.6.1, there is a buffer over-read while parsing malformed TCP, UDP, and IPv6 packets in the functions `extract_l3_ipv6`, `extract_l4_tcp`, and `extract_l4_udp` that can be triggered remotely.

2017-05-29 CVE-2017-9263 Improper Input Validation vulnerability in Openvswitch 2.7.0
In Open vSwitch (OvS) 2.7.0, while parsing an OpenFlow role status message, there is a call to the abort() function for undefined role status reasons in the function `ofp_print_role_status_message` in `lib/ofp-print.c` that may be leveraged toward a remote DoS attack by a malicious switch.
low complexity
openvswitch CWE-20
6.5
2017-05-29 CVE-2016-10377 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Openvswitch 2.5.0
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.
low complexity
openvswitch CWE-119
8.8
2017-05-23 CVE-2017-9214 Integer Underflow (Wrap or Wraparound) vulnerability in multiple products
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`.
