critical Nessus Plugin ID 158168

Language:

Synopsis

The remote host has an application installed that is affected by multiple vulnerabilities.

Description

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.

Solution

Upgrade to Zoom Client for Meetings 5.8.4 or later.
