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.
rdesktop through 1.9.0 contains a heap out-of-bounds read vulnerability in process_raw_bmpcache() in orders.c that allows malicious RDP servers to crash clients. Attackers can send a raw bitmap cache order declaring large width, height, and bpp values with a tiny payload, causing memcpy() to read past the receive buffer and crash the client.
rdesktop through 1.9.0 contains a heap out-of-bounds read vulnerability in process_plane() in bitmap.c that allows malicious RDP servers to crash clients by sending malformed 32 bpp compressed bitmaps. Attackers can declare a large bitmap geometry with a short compressed body in bitmap update PDUs or bitmap cache orders, causing unbounded reads past the receive buffer and denial of service.
RDesktop version 1.8.4 contains multiple out-of-bound access read vulnerabilities in its code, which results in a denial of service (DoS) condition. This attack appear to be exploitable via network connectivity. These issues have been fixed in version 1.8.5
rdesktop versions up to and including v1.8.3 contain a Buffer Overflow over the global variables in the function seamless_process_line() that results in memory corruption and probably even a remote code execution.
rdesktop versions up to and including v1.8.3 contain an Integer Underflow that leads to a Heap-Based Buffer Overflow in the function seamless_process() and results in memory corruption and probably even a remote code execution.
rdesktop versions up to and including v1.8.3 contain an Integer Underflow that leads to a Heap-Based Buffer Overflow in the function rdpsnddbg_process() and results in memory corruption and probably even a remote code execution.
rdesktop versions up to and including v1.8.3 contain an Integer Underflow that leads to a Heap-Based Buffer Overflow in the function lspci_process() and results in memory corruption and probably even a remote code execution.
rdesktop versions up to and including v1.8.3 contain an Out-Of-Bounds Read in the function process_demand_active() that results in a Denial of Service (segfault).
rdesktop versions up to and including v1.8.3 contain an Integer Overflow that leads to a Heap-Based Buffer Overflow in the function rdp_in_unistr() and results in memory corruption and possibly even a remote code execution.
rdesktop versions up to and including v1.8.3 contain several Out-Of- Bounds Reads in the file secure.c that result in a Denial of Service (segfault).
rdesktop versions up to and including v1.8.3 contains several Integer Signedness errors that lead to Out-Of-Bounds Reads in the file mcs.c and result in a Denial of Service (segfault).
rdesktop versions up to and including v1.8.3 contain an Out-Of-Bounds Read in the function ui_clip_handle_data() that results in an information leak.
rdesktop versions up to and including v1.8.3 contain a Heap-Based Buffer Overflow in function ui_clip_handle_data() that results in a memory corruption and probably even a remote code execution.
rdesktop versions up to and including v1.8.3 contain an Out-Of-Bounds Read in function process_secondary_order() that results in a Denial of Service (segfault).
rdesktop versions up to and including v1.8.3 contain an Out-Of-Bounds Read in function rdpsnd_process_ping() that results in an information leak.
rdesktop versions up to and including v1.8.3 contain a Heap-Based Buffer Overflow in function process_plane() that results in a memory corruption and probably even a remote code execution.
rdesktop versions up to and including v1.8.3 contain an Out-Of-Bounds Read in function process_bitmap_updates() that results in a Denial of Service (segfault).
rdesktop versions up to and including v1.8.3 contain an Integer Overflow that leads to a Heap-Based Buffer Overflow in function process_bitmap_updates() and results in a memory corruption and probably even a remote code execution.
rdesktop versions up to and including v1.8.3 contain an Integer Overflow that leads to an Out-Of-Bounds Write in function process_bitmap_updates() and results in a memory corruption and possibly even a remote code execution.
