USN-8561-2: FreeRDP regression

USN-8561-1 fixed vulnerabilities in FreeRDP. Unfortunately, the upgrade to
version 3.30.0 introduced a regression in the clipboard functionality. This
update fixes the problem.

We apologize for the inconvenience.

Original advisory details:

It was discovered that FreeRDP contained multiple security issues. An
attacker could possibly use these issues to obtain sensitive information,
cause FreeRDP to crash, resulting in a denial of service, or execute
arbitrary code.
