openSUSE Security Update: NRPE metacharacter filtering omission ______________________________________________________________________________ Announcement ID: openSUSE-SU-2013:0621-1 Rating: important References: #807241 Cross-References: CVE-2013-1362 Affected Products: openSUSE 12.2 openSUSE 12.1 ______________________________________________________________________________ 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. Patch Instructions: To install this openSUSE Security Update use YaST online_update.
