snowflake-connector-net is the Snowflake Connector for .NET. Versions starting from 2.1.2 to before 4.4.1, are vulnerable to a Time-of-Check to Time-of-Use (TOCTOU) race condition. When using the Easy Logging feature on Linux and macOS, the Connector reads logging configuration from a user-provided file. On Linux and macOS, the Connector verifies that the configuration file can be written to only by its owner. That check was vulnerable to a TOCTOU race condition and failed to verify that the file owner matches the user running the Connector. This could allow a local attacker with write access
