Open vSwitch Buffer Over Read Vulnerability

Open vSwitch OvS is an open source implementation of a distributed virtual multilayer switch. A buffer over-read vulnerability exists in the decodebundle function in lib/ofp-actions.c in Open vSwitch OvS 2.7.x =2.7.6 during decoding of BUNDLE operations. No detailed vulnerability details are...

CVE-2018-17206

An issue was discovered in Open vSwitch OvS 2.7.x through 2.7.6. The decodebundle function inside lib/ofp-actions.c is affected by a buffer over-read issue during BUNDLE action decoding...

DEBIAN-CVE-2018-17205

An issue was discovered in Open vSwitch OvS 2.7.x through 2.7.6, affecting ofprotoruleinsert in ofproto/ofproto.c. During bundle commit, flows that are added in a bundle are applied to ofproto in order. If a flow cannot be added e.g., the flow action is a go-to for a group id that does not exist,...

Design/Logic Flaw

An issue was discovered in Open vSwitch OvS 2.7.x through 2.7.6, affecting parsegrouppropntrselectionmethod 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 comma...

CVE-2018-17205

Open vSwitch CVE-2018-17205 affects 2.7.x–2.7.6 in the bundle commit path (ofproto_rule_insert__) where, if a flow fails to be added, OvS reverts previous flows from the same bundle. While reinserting old flows, an assertion failure on rule state != RULE_INITIALIZED occurs because the old flow st...

CVE-2018-17204

Open vSwitch (OVS) 2.7.x–2.7.6 is affected by CVE-2018-17204 due to a logic error in parse_group_prop_ntr_selection_method within lib/ofp-util.c. During decoding of a group mod, the code validates the group type/command only after the full group mod is parsed, but the OpenFlow 1.5 decoder may use...
