2. Relevant releases/architectures:

MRG Grid for RHEL 6 Server v.2 - i386, x86_64

3. Description:

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.
