CWE-190

Description

A size check in the client-side authentication path of the MongoDB C Driver can wrap around, so an unusually large user-name value is accepted and copied past the end of a small buffer. A party able to set the driver's connection settings may cause the application that embeds the driver to terminate unexpectedly. Reaching this code requires a build in which the optional external SASL authentication backend is present and a connection configured to use it.

Affected configurations

• mongodb c driver (>= 1.10.0 < 1.30.10) • mongodb c driver (>= 2.2.0 < 2.5.3)
