Description Gianluca Gabrielli 2021-02-08 17:27:24 UTC

CVE-2021-20206

A flaw was found in libcni. A user may  be able to change the "type:" field in a CNI configuration to an arbitrary path and could execute arbitrary binaries on a host.

Upstream patch:

https://github.com/containernetworking/cni/pull/808

Comment 1 Gianluca Gabrielli 2021-02-08 17:29:10 UTC

Upstream patch: https://github.com/containernetworking/cni/commit/ada67263b12ff0c65f1256e120f6d9f7f0277388.patch

Comment 2 Gianluca Gabrielli 2021-02-08 17:33:32 UTC

An improper limitation of path name vulnerability was found in containernetworking/cni. 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. An attacker can use this to execute other existing binaries other than the cni plugins/types such as `reboot`.

Comment 6 Vincent Moutoussamy 2022-08-25 09:05:06 UTC

@Aleksa, please take a look at this one.

Comment 7 Vincent Moutoussamy 2022-09-19 09:15:04 UTC

@Aleksa ping?

Comment 9 Aleksa Sarai 2022-09-21 01:03:00 UTC

Podman 3.1.0 and later have a fix for this, but the simplest solution (which will help with some other podman fixes) is to update podman and its dependencies in SLES to the latest versions.

@Aleksa, I feel like we deserve to at least update podman to the latest 2.x release for 15GA and 15SP1, we are providing 2.1.1 and the latest is https://github.com/containers/podman/releases/tag/v2.2.1. And would that provide a fix for this CVE?

Comment 11 Vincent Moutoussamy 2022-09-27 08:09:49 UTC

well we will update podman to 3.4.7 for SLE15SP1 https://maintenance.suse.de/request/278583/
