(CMS), formerly Acano Conferencing Server, could allow an authenticated, remote attacker to retrieve memory
contents, which could lead to the disclosure of confidential information. In addition, the attacker could
potentially cause the application to crash unexpectedly, resulting in a denial of service (DoS) condition. The
attacker would need to be authenticated and have a valid session with the Web Bridge.");
