CBL Mariner 2.0 Security Update: kubevirt (CVE-2022-1798)

medium Nessus Plugin ID 173492

Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

The version of kubevirt installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2022-1798 advisory.

 - A path traversal vulnerability in KubeVirt versions up to 0.56 (and 0.55.1) on all platforms allows a user able to configure the kubevirt to read arbitrary files on the host filesystem which are publicly readable or which are readable for UID 107 or GID 107. /proc/self/<> is not accessible. (CVE-2022-1798)

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

Solution

Update the affected packages.
