    * CVE-2021-41159: fix client out of memory
    CVE(s):
    CVE-2021-41159
    FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license.
    All FreeRDP clients prior to version 2.4.1 using gateway connections (`/gt:rpc`) fail to validate input
    data. A malicious gateway might allow client memory to be written out of bounds. This issue has been
    resolved in version 2.4.1. If you are unable to update then use `/gt:http` rather than /gt:rdp connections
    if possible or use a direct connection without a gateway.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

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