Vulnerabilities exist in the authentication module that may improperly process malformed or truncated input. An authenticated remote attacker could exploit these vulnerabilities by providing specially crafted input from a compromised or hostile authentication server. Successful exploitation could result in a Denial-of-Service or potential remote code execution with elevated privileges.
