yum update-minimal --security does not update a package

Issue

• yum update-minimal --security fail to update a package for wich an existing RHSA has been released but not yet updated on the system.

• Consider the following:

[root@fastvm-rhel-7-9-51 ~]# yum check-update -q --security

NetworkManager-config-server.noarch                                       1:1.18.8-1.el7                                        rhel-7-server-rpms

[root@fastvm-rhel-7-9-51 ~]# rpm -q NetworkManager-config-server
NetworkManager-config-server-1.4.0-14.el7_3.x86_64

• We see the current version of NetworkManager (1.4.0-14.el7_3.x86_64) should be updated.
• The RHSA associated with the fix is RHSA-2018:3665 . It provide version 1.12.0-8.el7_6.noarch of the package.
• yum update-minimal --security fail to install the correct version, but install the latest one:

[root@fastvm-rhel-7-9-51 ~]# yum update-minimal --security
