Rating:             important
References:         #807241 
Cross-References:   CVE-2013-1362
Affected Products:
                    openSUSE 11.4
______________________________________________________________________________

   An update that fixes one vulnerability is now available.

Description:

   NRPE (the Nagios Remote Plug-In Executor) allows the
   passing of $() to plugins/scripts which, if run under bash,
   will execute that shell command under a subprocess and pass
   the output as a parameter to the called script. Using this,
   it is possible to get called scripts, such as check_http,
   to execute arbitrary commands under the uid that
   NRPE/nagios is running as (typically, 'nagios').

   With this update NRPE will deny remote requests
   containing a bash command substitution.
