(RHSA-2013:1170) Important: mongodb and pymongo security and enhancement update

MongoDB is a NoSQL database. PyMongo provides tools for working with
MongoDB.

A flaw was found in the run() function implementation in MongoDB. A
database user permitted to send database queries to a MongoDB server could
use this flaw to crash the server or, possibly, execute arbitrary code with
the privileges of the mongodb user. (CVE-2013-1892)

A NULL pointer dereference flaw was found in PyMongo. An invalid DBRef
record received from a MongoDB server could cause an application using
PyMongo to crash. (CVE-2013-2132)

Note: In Red Hat Enterprise MRG Grid, MongoDB is not accessed by users
directly and is only accessed by other Grid services, such as Condor and
Cumin.

This update also adds the following enhancement:

• Previously, MongoDB was configured to listen for connections on all
  network interfaces. This could allow remote users to access the database if
  the firewall was configured to allow access to the MongoDB port (access is
  blocked by the default firewall configuration in Red Hat Enterprise Linux).
  This update changes the configuration to only listen on the loopback
  interface by default. (BZ#892767)

Users of Red Hat Enterprise MRG 2.3 for Red Hat Enterprise Linux 6 are
advised to upgrade to these updated packages, which contain backported
patches to resolve these issues and add this enhancement. After installing
this update, MongoDB will be restarted automatically.
