"The version of the Zoom Client installed on the remote host is prior to 5.8.4. It is, therefore, affected by the
following vulnerabilities:

  - An unspecified buffer overflow condition. An unauthenticated, remote attacker can exploit this to cause a
    denial of service condition or the execution of arbitrary code. (CVE-2021-34423)

  - An unspecified information disclosure vulnerability. An unauthenticated, remote attacker can exploit this
    to disclose potentially sensitive information. (CVE-2021-34424)

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