CVE-2018-17204 (retired)

Priority
Description
An issue was discovered in Open vSwitch (OvS) 2.7.x through 2.7.6,
affecting parse_group_prop_ntr_selection_method in lib/ofp-util.c. When
decoding a group mod, it validates the group type and command after the
whole group mod has been decoded. The OF1.5 decoder, however, tries to use
the type and command earlier, when it might still be invalid. This causes
an assertion failure (via OVS_NOT_REACHED). ovs-vswitchd does not enable
support for OpenFlow 1.5 by default.
