Hi,
The following vulnerability was published for freerdp2.
CVE-2021-41159[0]:
| 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.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
