CVE-2018-8787
FreeRDP prior to version 2.0.0-rc4 contains an Integer Overflow that leads to a Heap-Based Buffer Overflow in function gdi_Bitmap_Decompress() and results in a memory corruption and probably even a remote code execution.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (8.36%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
