[Bug 291265] [NEW] Buffer overflow in check_ntp_peer - Nagios can't check time servers in Intrepid

[Anderson]

Public bug reported:

Binary package hint: nagios-plugins-basic

I just upgraded my Nagios server from Ubuntu Hardy to Ubuntu Intrepid
and now, time server checks can't be done because of a problem in
check_ntp_peer:

$ /usr/lib/nagios/plugins/check_ntp_peer -H time.cefetrs.tche.br  
*** buffer overflow detected ***: /usr/lib/nagios/plugins/check_ntp_peer terminated
