openSUSE Security Update: NRPE metacharacter filtering omission



Announcement ID: openSUSE-SU-2013:0624-1

Rating: important

References: #807241

Cross-References: CVE-2013-1362

Affected Products:

openSUSE 11.4



An update that fixes one vulnerability is now available.




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.

Alternatively you can run the command listed for your product:


- openSUSE 11.4:


zypper in -t patch 2013-55


To bring your system up-to-date, use "zypper patch".
