Alpine: FreeRDP: security update to 2.4.0-r2 (deprecated)

high Tenable Cloud Security Plugin ID 400005

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- 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. (CVE-2021-41159)

- FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license.
In affected versions a malicious server might trigger out of bound writes in a connected client.
Connections using GDI or SurfaceCommands to send graphics updates to the client might send `0`
width/height or out of bound rectangles to trigger out of bound writes. With `0` width or heigth the
memory allocation will be `0` but the missing bounds checks allow writing to the pointer at this (not
allocated) region. This issue has been patched in FreeRDP 2.4.1. (CVE-2021-41160)
