How do i check redhat linux for software security updates?

  • Using the yum command with the option:

                  Implemented  so  you  could know if your machine had any updates
                  that needed to be  applied  without  running  it  interactively.
                  Returns exit value of 100 if there are packages available for an
                  update. Also returns a list of the packages  to  be  updated  in
                  list  format. Returns 0 if no packages are available for update.
                  Returns 1 if an error occurred.  Running in  verbose  mode  also
                  shows obsoletes.

    The command provides a summary at the end.

    $ sudo yum check-update --security
    No packages needed for security; 86 packages available
