CVE-2013-2132: Use of NullPointerException Catch to Detect NULL Pointer Dereference in Pymongo

May 14, 2022 (updated October 31, 2025)

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.”
