Overview
Affected versions of this package are vulnerable to Improper Enforcement of Message Integrity During Transmission in a Communication Channel via the negotiation process between GSSAPI and TLS encryption. An attacker can bypass intended authentication and encryption requirements by initiating a direct TLS connection, potentially resulting in data exchange with weaker security controls if TLS settings are less restrictive than GSSAPI settings.
