FreeRDP is a free implementation of the Remote Desktop Protocol (RDP),
released under the Apache license. Affected versions of FreeRDP are subject
to a Null Pointer Dereference leading a crash in the RemoteFX (rfx)
handling. Inside the rfx_process_message_tileset function, the program
allocates tiles using rfx_allocate_tiles for the number of numTiles. If
the initialization process of tiles is not completed for various reasons,
tiles will have a NULL pointer. Which may be accessed in further processing
and would cause a program crash. This issue has been addressed in versions
2.11.0 and 3.0.0-beta3. Users are advised to upgrade. There are no known
workarounds for this vulnerability.
