==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 26.04 LTS

- Ubuntu 22.04 LTS

Summary:

The CA certificates in the ca-certificates package were updated.

Software Description:

refreshes the included certificates to those contained in the 2.86 version
of the Mozilla certificate authority bundle.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 26.04 LTS
  ca-certificates                 20260601~26.04.1

Ubuntu 22.04 LTS
  ca-certificates                 20260601~22.04.1
