FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP
based clients that use a version of FreeRDP prior to 3.5.0 or 2.11.6 and
have connections to servers using the NSC codec are vulnerable to integer
underflow. Versions 3.5.0 and 2.11.6 patch the issue. As a workaround, do
not use the NSC codec (e.g. use -nsc).

Notes

Author	Note
	Priority reason: FreeRDP developers have rated this as being a low severity issue
