Resúmen:

SELinux is preventing /usr/bin/python from connecting to port 18475.

Descripción Detallada:

SELinux has denied yum from connecting to a network port 18475 which does not
have an SELinux type associated with it. If yum should be allowed to connect on
18475, use the semanage command to assign 18475 to a port type that abrt_t can
connect to (http_port_t).
If yum is not supposed to connect to 18475, this could signal a intrusion
attempt.

Permitiendo Acceso:

If you want to allow yum to connect to 18475, you can execute
semanage port -a -t PORT_TYPE -p tcp 18475
where PORT_TYPE is one of the following: http_port_t.
