From ${URL} : client/X11/xf_graphics.c:xf_Pointer_New() performs a heap allocation this way: void xf_Pointer_New(rdpContext* context, rdpPointer* pointer) { XcursorImage ci; […] ci.width = pointer->width; ci.height = pointer->height; […] ci.pixels = (XcursorPixel*) malloc(ci.width * ci.height * 4); The width and height members are read from the wire. Both are 16 bit, but because of the multiplication with 4, the allocation still overflows (on 32 bit and 64 bit). xf_Bitmap_Decompress() appears to have a similar issue. @maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
Here are the commits for this in to upstream https://github.com/FreeRDP/FreeRDP/pull/1874
This one will be easier to apply. Just waiting for it to be merged upstream. https://github.com/FreeRDP/FreeRDP/pull/1891
