  - A session spoofing vulnerability exists. An attacker can exploit this to perform actions with the     privileges of another user. (CVE-2021-38650)

  - A remote code execution vulnerability. An attacker can exploit this to bypass authentication and execute     unauthorized arbitrary commands. (CVE-2021-38646, CVE-2021-38655, CVE-2021-38658, CVE-2021-38659,       CVE-2021-38660)

  - An information disclosure vulnerability in the graphics component. An attacker can exploit this to     disclose sensitive information. (CVE-2021-38657)

The Microsoft Office product installed on the remote host is affected by multiple vulnerabilities, as follows:

  - A spoofing vulnerability in Microsoft Office that can be exploited by a remote, low privileged attacker.
    (CVE-2021-38650)

  - A remote code execution vulnerability in Microsoft Excel that can be exploited by a local, unprivileged     attacker. (CVE-2021-38655)
