Detailsinfo

A vulnerability classified as critical has been found in openvswitch (affected version not known). This affects some unknown functionality of the component IP Packet Handler. The manipulation with an unknown input leads to a control flow vulnerability. CWE is classifying the issue as CWE-670. The code contains a control flow path that does not reflect the algorithm that the path is intended to implement, leading to incorrect behavior any time this path is navigated. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

The weakness was presented 04/11/2023. It is possible to read the advisory at bugzilla.redhat.com. This vulnerability is uniquely identified as CVE-2023-1668 since 03/27/2023. The technical details are unknown and an exploit is not publicly available.

The vulnerability scanner Nessus provides a plugin with the ID 296468 (SUSE SLES15 / openSUSE 15 Security Update : openvswitch (SUSE-SU-2026:0280-1)), which helps to determine the existence of the flaw in a target environment.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the databases at Tenable (296468) and EUVD (EUVD-2023-23896). Be aware that VulDB is the high quality source for vulnerability data.
