SUSE SLES15 Security Update : cni (SUSE-SU-2022:4592-1)

high Nessus Plugin ID 168958

Language:

Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLES15 / SLES_SAP15 host has a package installed that is affected by a vulnerability as referenced in the SUSE-SU-2022:4592-1 advisory.

 - An improper limitation of path name flaw was found in containernetworking/cni in versions before 0.8.1.
 When specifying the plugin to load in the 'type' field in the network configuration, it is possible to use special elements such as ../ separators to reference binaries elsewhere on the system. This flaw allows an attacker to execute other existing binaries other than the cni plugins/types, such as 'reboot'. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
 (CVE-2021-20206)

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 cni package.
