Package : openvswitch Version : 2.10.7+ds1-0+deb10u5 CVE ID : CVE-2023-5366 Debian Bug :

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.

For Debian 10 buster, this problem has been fixed in version 2.10.7+ds1-0+deb10u5.

We recommend that you upgrade your openvswitch packages.

For the detailed security status of openvswitch please refer to its security tracker page at:
