SUSE SLES15 Security Update : openvswitch (SUSE-SU-2023:2275-1)

critical Nessus Plugin ID 176264

Language:

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:2275-1 advisory.

- An out-of-bounds read in Organization Specific TLV was found in various versions of OpenvSwitch.
(CVE-2022-4337)

- An integer underflow in Organization Specific TLV was found in various versions of OpenvSwitch.
(CVE-2022-4338)

- 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 these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
