"The version of Google Earth Pro installed on the remote host is prior to 7.3.3. It is, therefore, affected by
the following vulnerabilities :

  - A DLL hijacking vulnerability exists in the Windows installer due to the use of an untrusted search path.
    An unauthenticated, local attacker can exploit this, via inserting a malicious file, to bypass
    authentication and execute arbitrary code. (CVE-2020-8895)

  - A buffer overflow condition exists in khcrypt implementation. An unauthenticated, adjacent attacker can
    exploit this, via a specially crafted key, to execute a MitM attack. (CVE-2020-8896)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
