Descriptions

In FreeRDP before 2.1.0, there is an out-of-bound read in irp functions (parallel_process_irp_create, serial_process_irp_create, drive_process_irp_write, printer_process_irp_write, rdpei_recv_pdu, serial_process_irp_write). This has been fixed in 2.1.0.

En FreeRDP versiones anteriores a 2.1.0, se presenta una lectura fuera de límite en las funciones de irp (parallel_process_irp_create, serial_process_irp_create, drive_process_irp_write, printer_process_irp_write, rdpei_recv_pdu, serial_process_irp_write). Esto ha sido corregido en la versión 2.1.0.

FreeRDP is a free implementation of the Remote Desktop Protocol, released under the Apache license. The xfreerdp client can connect to RDP servers such as Microsoft Windows machines, xrdp, and VirtualBox. The vinagre packages provide the Vinagre remote desktop viewer for the GNOME desktop. Issues addressed include double free, integer overflow, and out of bounds read vulnerabilities.
