2021-03-18 CVE-2020-27827 A flaw was found in multiple versions of OpenvSwitch. Specially crafted LLDP packets can cause memory to be lost when allocating data to handle specific optional TLVs, potentially causing a denial of service. The highest threat from this vulnerability is to system availability. Fedora, Lldpd, Openvswitch, Enterprise_linux, Openshift_container_platform, Openstack, Virtualization, Simatic_hmi_unified_comfort_panels_firmware, Simatic_net_cp_1243\-1_firmware, Simatic_net_cp_1243\-8_irc_firmware, Simatic_net_cp_1542sp\-1_firmware, Simatic_net_cp_1542sp\-1_irc_firmware, Simatic_net_cp_1543\-1_firmware, Simatic_net_cp_1543sp\-1_firmware, Simatic_net_cp_1545\-1_firmware, Sinumerik_one_firmware, Tim_1531_irc_firmware 7.5
2022-09-08 CVE-2019-25076 The TSS (Tuple Space Search) algorithm in Open vSwitch 2.x through 2.17.2 and 3.0.0 allows remote attackers to cause a denial of service (delays of legitimate traffic) via crafted packet data that requires excessive evaluation time within the packet classification algorithm for the MegaFlow cache, aka a Tuple Space Explosion (TSE) attack. Openvswitch 5.8
2022-08-29 CVE-2022-0669 A flaw was found in dpdk. This flaw allows a malicious vhost-user master to attach an unexpected number of fds as ancillary data to VHOST_USER_GET_INFLIGHT_FD / VHOST_USER_SET_INFLIGHT_FD messages that are not closed by the vhost-user slave. By sending such messages continuously, the vhost-user master exhausts available fd in the vhost-user slave process, leading to a denial of service. Data_plane_development_kit, Openvswitch, Openshift_container_platform 6.5
2022-08-23 CVE-2021-3905 A memory leak was found in Open vSwitch (OVS) during userspace IP fragmentation processing. An attacker could use this flaw to potentially exhaust available memory by keeping sending packet fragments. Ubuntu_linux, Fedora, Openvswitch, Enterprise_linux_fast_datapath 7.5
2017-05-23 CVE-2017-9214 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`. Debian_linux, Openvswitch, Openstack, Virtualization, Virtualization_manager 9.8
2018-09-19 CVE-2018-17204 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. Ubuntu_linux, Debian_linux, Openvswitch, Openstack 4.3
2018-09-19 CVE-2018-17205 An issue was discovered in Open vSwitch (OvS) 2.7.x through 2.7.6, affecting ofproto_rule_insert__ 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), OvS tries to revert back all previous flows that were successfully applied from the same bundle. This is possible since OvS maintains list of old flows that were replaced by flows from the... Ubuntu_linux, Openvswitch, Openstack 7.5
2018-09-19 CVE-2018-17206 An issue was discovered in Open vSwitch (OvS) 2.7.x through 2.7.6. The decode_bundle function inside lib/ofp-actions.c is affected by a buffer over-read issue during BUNDLE action decoding. Ubuntu_linux, Debian_linux, Openvswitch, Openstack 4.9
2021-07-20 CVE-2021-36980 Open vSwitch (aka openvswitch) 2.11.0 through 2.15.0 has a use-after-free in decode_NXAST_RAW_ENCAP (called from ofpact_decode and ofpacts_decode) during the decoding of a RAW_ENCAP action. Openvswitch 5.5
2021-02-11 CVE-2020-35498 A vulnerability was found in openvswitch. A limitation in the implementation of userspace packet parsing can allow a malicious user to send a specially crafted packet causing the resulting megaflow in the kernel to be too wide, potentially causing a denial of service. The highest threat from this vulnerability is to system availability. Debian_linux, Fedora, Openvswitch 7.5
