Open vSwitch provides standard network bridging functions and support for the OpenFlow protocol for remote per-flow control of traffic.
Security Fix(es):
An unsigned int wrap around leading to a buffer over-read was found when parsing OFPT_QUEUE_GET_CONFIG_REPLY messages in Open vSwitch (OvS). An attacker could use this flaw to cause a remote DoS. (CVE-2017-9214)
In Open vSwitch (OvS), 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. (CVE-2017-9263)
A buffer over-read flaw was found in Open vSwitch (OvS) while parsing the group mod OpenFlow messages sent from the controller. An attacker could use this flaw to cause a Denial of Service (DoS). (CVE-2017-9265)
