bson/_cbsonmodule.c in the mongo-python-driver (aka. pymongo) before 2.5.2, as used in MongoDB, allows context-dependent attackers to cause a denial of service (NULL pointer dereference and crash) via vectors related to decoding of an "invalid DBRef."

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - bson/_cbsonmodule.c in the mongo-python-driver (aka. pymongo) before 2.5.2, as used in MongoDB, allows
    context-dependent attackers to cause a denial of service (NULL pointer dereference and crash) via vectors
    related to decoding of an "invalid DBRef." (CVE-2013-2132)

Updated mongodb and pymongo packages that fix two security issues and add one enhancement are now available for Red Hat Enterprise MRG 2.3 for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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.

This update of pymongo fixes a NULL pointer issue.

  - Add Fix-null-pointer-when-decoding-invalid-DBRef.patch

  - Fixed user-triggerable NULL pointer dereference due to     utter plebbery (CVE-2013-2132, bnc#822798)

Jibbers McGee discovered that PyMongo incorrectly handled certain invalid DBRefs. An attacker could use this issue to cause PyMongo to crash, resulting in a denial of service.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Jibbers McGee discovered that PyMongo, a high-performance schema-free document-oriented data store, is prone to a denial-of-service vulnerability.

An attacker can remotely trigger a NULL pointer dereference causing MongoDB to crash.

The oldstable distribution (squeeze) is not affected by this issue.
