| CVE-2020-35498 | 3 Debian, Fedoraproject, Openvswitch | 3 Debian Linux, Fedora, Openvswitch | 2023-11-26 | 7.8 HIGH | 7.5 HIGH |
| 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. | |||||
| CVE-2021-3905 | 4 Canonical, Fedoraproject, Openvswitch and 1 more | 4 Ubuntu Linux, Fedora, Openvswitch and 1 more | 2023-11-26 | N/A | 7.5 HIGH |
| 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. | |||||
| CVE-2020-27827 | 5 Fedoraproject, Lldpd Project, Openvswitch and 2 more | 27 Fedora, Lldpd, Openvswitch and 24 more | 2023-11-26 | 7.1 HIGH | 7.5 HIGH |
| 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. | |||||
| CVE-2018-17205 | 3 Canonical, Openvswitch, Redhat | 3 Ubuntu Linux, Openvswitch, Openstack | 2021-08-04 | 5.0 MEDIUM | 7.5 HIGH |
| 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 bundle. While reinserting old flows, OvS has an assertion failure due to a check on rule state != RULE_INITIALIZED. This would work for new flows, but for an old flow the rule state is RULE_REMOVED. The assertion failure causes an OvS crash. | |||||
| CVE-2016-10377 | 1 Openvswitch | 1 Openvswitch | 2017-06-08 | 5.8 MEDIUM | 8.8 HIGH |
| 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. | |||||
