CVE-2020-11047

FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. The xfreerdp client can connect to RDP servers such as Microsoft Windows machines, xrdp, and VirtualBox.

The vinagre packages provide the Vinagre remote desktop viewer for the GNOME desktop.

The following packages have been upgraded to a later upstream version: freerdp (2.1.1). (BZ#1834287)

In FreeRDP after 1.1 and before 2.0.0, there is an out-of-bounds read in autodetect_recv_bandwidth_measure_results. A malicious server can extract up to 8 bytes of client memory with a manipulated message by providing a short input and reading the measurement result data. This has been patched in 2.0.0.

It was discovered that FreeRDP incorrectly handled certain memory operations. A remote attacker could use this issue to cause FreeRDP to crash, resulting in a denial of service, or possibly exeucte arbitrary code.

The freerdp package has been updated to version 2.1.2 to fix these issues.

Also, the remmina package has been updated to version 1.4.7 for compatibility with the updated freerdp.
