______________________________________________________________________________

 

Announcement ID: openSUSE-SU-2013:0621-1

Rating: important

References: #807241

Cross-References: CVE-2013-1362

Affected Products:

openSUSE 12.2

______________________________________________________________________________

 

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.
