SUSE SLED15 / SLES15 / openSUSE 15 Security Update : openvswitch (SUSE-SU-2023:2296-1)

high Nessus Plugin ID 176410


The remote SUSE host is missing a security update.


The remote SUSE Linux SLED15 / SLES15 / openSUSE 15 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2023:2296-1 advisory.

- A flaw was found in openvswitch (OVS). When processing an IP packet with protocol 0, OVS will install the datapath flow without the action modifying the IP header. This issue results (for both kernel and userspace datapath) in installing a datapath flow matching all IP protocols (nw_proto is wildcarded) for this flow, but with an incorrect action, possibly causing incorrect handling of other IP packets with a != 0 IP protocol that matches this dp flow. (CVE-2023-1668)

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


Update the affected packages.
