Description
A flaw was found in FreeRDP. A remote attacker could exploit a use-after-free vulnerability in the xf_SetWindowMinMaxInfo function. This occurs when a freed window pointer is dereferenced because the main thread concurrently deletes a window while the Remote Desktop Protocol (RAIL) channel thread is still using the pointer. This flaw can lead to a denial of service.
