Debian LTS Advisory DLA-3734-1 [email protected]
https://www.debian.org/lts/security/ Tobias Frost
February 17, 2024 https://wiki.debian.org/LTS

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:
