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.

Ein Angreifer kann mehrere Schwachstellen in verschiedenen MongoDB Treibern (Python Driver, PHP Driver, C Driver, Compass und Laravel) ausnutzen, um einen Denial of Service Angriff durchzuführen, um Daten zu manipulieren, um beliebigen Programmcode auszuführen und um einen nicht näher spezifizierten Angriff durchzuführen.
