Component:

'Dex', 'containers', 'addons'

What happened:

Please see this post for more: GHSA-m9hp-7r99-94h5
MetalK8s users implementing the Dex SAML connector could be impacted since they run a Dex version inferior to v2.27.0

What was expected:

Dex is expected to be secured and up to date.

Steps to reproduce

None

Resolution proposal (optional):

  • Bump Dex version to v2.27.0.

Important to note this only affects the SAML connector of Dex, which we're not using in the Scality products: any integration of the product with a SAML IdP would go through another user management system, to which Dex connects through OIDC.

However, indeed upgrading is the right action 👍

Because of "CVE-2020-15216" we need to use a newer Dex image, note that
at this time no stable repo exists for Dex helm3 chart so we still use
the deprected chart where we only bump the Dex image version

Fixes: #2985
