Attack-Flow Graph

Executive Summary

This vulnerability is caused by inconsistent validation of object sizes in the time series processing logic of MongoDB Server. It may allow oversized BSON documents to be processed later than expected, which can trigger an assertion failure and cause the MongoDB process to terminate unexpectedly.

Impact Analysis

The impact of this vulnerability is that it can cause the MongoDB server process to terminate unexpectedly due to assertion failures when processing oversized BSON documents. This can lead to denial of service, disrupting availability of the database service.
