How to fix?

There is no fixed version for Echo:latest pymongo.

NVD Description

Note: Versions mentioned in the description apply only to the upstream pymongo package and not the pymongo package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

An integer overflow in the BSON document encoding component of the MongoDB Python Driver's bundled native extension may occur when a single document is built from an unusually large amount of caller-supplied data. Size arithmetic is performed in a signed 32-bit type, and the guard meant to catch the overflow is written in a form whose behavior is not defined by the C language standard. A party with no privileges who can place a very large value into data that an application encodes may, depending on how the native extension was built, cause a write outside the bounds of an allocated buffer inside the application's own process.
