CVE-2023-5366 |
A flaw was found in Open vSwitch that allows ICMPv6 Neighbor Advertisement packets between virtual machines to bypass OpenFlow rules. This issue may allow a local attacker to create specially crafted packets with a modified or spoofed target IP address field that can redirect ICMPv6 traffic to arbitrary IP addresses.

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.

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. Published: August 23, 2022; 12:15:10 PM -0400 |
V4.0:(not available) V3.1: 7.5 HIGH V2.0:(not available) |
CVE-2017-14970 |
In lib/ofp-util.c in Open vSwitch (OvS) before 2.8.1, there are multiple memory leaks while parsing malformed OpenFlow group mod messages. NOTE: the vendor disputes the relevance of this report, stating "it can only be triggered by an OpenFlow controller, but OpenFlow controllers have much more direct and powerful ways to force Open vSwitch to allocate memory, such as by inserting flows into the flow table."

CVE-2016-2074 |
Buffer overflow in lib/flow.c in ovs-vswitchd in Open vSwitch 2.2.x and 2.3.x before 2.3.3 and 2.4.x before 2.4.1 allows remote attackers to execute arbitrary code via crafted MPLS packets, as demonstrated by a long string in an ovs-appctl command. Published: July 03, 2016; 5:59:10 PM -0400 |
