Systems running rdesktop 1.9.0 or earlier as an RDP client connecting to servers you do not control. The flaw is in the client's handling of server data, so the risk comes from the server side of the connection. Teams that never use rdesktop, or only connect to their own trusted RDP hosts, are much less exposed.

rdesktop through 1.9.0 contains a heap out-of-bounds read vulnerability in process_bmpcache2() in orders.c that allows malicious RDP servers to crash clients via crafted revision-2 bitmap cache orders. Attackers can send an uncompressed order with large width/height or an underflowing mode nibble and short payload, causing memcpy() reads past the receive buffer and denial of service.
