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.
