Summary

Details

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.

Summary

openvswitch vulnerabilities

Details

Timothy Redaelli and Haresh Khandelwal discovered that Open vSwitch incorrectly handled certain crafted Geneve packets when hardware offloading via the netlink path is enabled. A remote attacker could possibly use this issue to cause Open vSwitch to crash, leading to a denial of service. (CVE-2023-3966)

It was discovered that Open vSwitch incorrectly handled certain ICMPv6 Neighbor Advertisement packets. A remote attacker could possibly use this issue to redirect traffic to arbitrary IP addresses. (CVE-2023-5366)
