Debian dla-3734 : openvswitch-common - security update

medium Nessus Plugin ID 190675


The remote Debian host is missing a security-related update.


The remote Debian 10 host has packages installed that are affected by a vulnerability as referenced in the dla-3734 advisory.

- 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-2023-5366)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.


Upgrade the openvswitch-common packages.
