Descriptions

In FreeRDP before 2.1.0, there is an out-of-bounds read in cliprdr_read_format_list. Clipboard format data read (by client or server) might read data out-of-bounds. This has been fixed in 2.1.0.

En FreeRDP versiones anteriores a 2.1.0, se presenta una lectura fuera de límites en la función cliprdr_read_format_list. Los datos de formato Clipboard leídos (por el cliente o el servidor) podrían leer datos fuera de límites. 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.
