"This updated package fixes the following bugs :

  - after a NIS server change, for example, after a server
    failure, ypbind corrupted files in the
    '/var/yp/binding/' directory. As well, these files were
    not updated, possibly causing old information to be
    retained. In these situations, glibc attempted to read
    the incorrect information, resulting in errors such as
    'RPC: Unable to receive; errno = Connection refused'.

  - by default, NIS clients pinged NIS servers every 20
    seconds. In large deployments, this added extra load,
    and could possibly cause a denial of service. In this
    updated package, a new 'ypbind' option,
    '-ping-interval', has been added, which allows
    administrators to configure the ping interval value."
