The following packages have been upgraded to a later upstream version: freerdp (2.2.0). (BZ#1881971)

Security Fix(es):

* freerdp: out of bound reads resulting in accessing memory location outside of static array PRIMARY_DRAWING_ORDER_FIELD_BYTES (CVE-2020-11095)

* freerdp: out of bounds read in PRIMARY_DRAWING_ORDER_FIELD_BYTES (CVE-2020-11097)

* freerdp: out of bounds read in license_read_new_or_upgrade_license_packet (CVE-2020-11099)

Affected: CleanStart: freerdp

Security vulnerability affects the freerdp package. In FreeRDP less than or equal to 2.

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
