In FreeRDP less than or equal to 2.1.2, an integer overflow exists due to missing input sanitation in rdpegfx channel. All FreeRDP clients are affected. The input rectangles from the server are not checked against local surface coordinates and blindly accepted. A malicious server can send data that will crash the client later on (invalid length arguments to a `memcpy`) This has been fixed in 2.2.0. As a workaround, stop using command line arguments /gfx, /gfx-h264 and /network:auto

Title: FreeRDP vulnerabilities
Summary: Several security issues were fixed in FreeRDP.
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 execute arbitrary
code.
Instructions: This update uses a new upstream release, which includes additional bug
fixes. In general, a standard system update will make all the necessary
changes.
