Description Agostino Sarubbo gentoo-dev 2013-06-01 19:09:56 UTC
From ${URL} :

A user triggerable null pointer occurs when parsing invalid DBref records. 
This was reported by Jibbers McGee.

This can be triggered in Mongo shell:
db.python532.insert({x : {"$ref" : "whatever"} });

Or in Python shell:
import pymongo
pymongo.MongoClient().test.python532.find_one()

A workaround is reportedly available:
Add "process_dbrefs=False" to all the drivers

External reference:
https://jira.mongodb.org/browse/PYTHON-532

A source code update is available at:
https://github.com/mongodb/mongo-python-driver/commit/a060c15ef87e0f0e72974c7c0e57fe811bbd06a2


@maintainer(s): after the bump, in case we need to stabilize the package, please say explicitly if it is ready for the stabilization or not.

CVE-2013-2132 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-2132):
  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."
