Description
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, a buffer overread in `freerdp_image_copy_from_icon_data()` (libfreerdp/codec/color.c) can be triggered by crafted RDP Window Icon (TS_ICON_INFO) data. The bug is reachable over the network when a client processes icon data from an RDP server (or from a man-in-the-middle). Version 3.23.0 fixes the issue.
