Summary
An authenticated user with standard read/write privileges can cause the mongod process to terminate due to an out-of-memory condition by sending a crafted aggregation command. MongoDB's libmongocrypt library insufficiently validates payload-supplied values, which can result in an excessively large memory allocation.
